Remarks by the Physical Division Chair for the Las Vegas, ACS National Meeting, September, 1997

George Flynn

The Division of Physical Chemistry sponsors a rich selection of symposia at the two national ACS meetings held each year. This is by far the most important and successful activity of the Division. You can help to guarantee the continued breadth and depth of these symposia by sending your suggestions for future topics to the Division Secretary, Mark Gordon. Please include the names of potential organizers as well as possible speakers with your suggestions. Remember that the Program Chairs for the Division operate with a 1-2 year lead time for most symposia. So in making your suggestions, please consider topics that will be timely in 1999 and 2000. The success of a symposium and the revenue it generates for the Physical Division are determined by the number of people attending the symposium sessions. Please come to the ACS national meetings and attend the symposia sponsored by the Division!

I wanted to alert you to two actions taken by the Physical Division's Executive Committee at the San Francisco Meeting in April. The first regards membership in the Division. We have experienced a healthy growth over the past year and we are now approaching the break point for division size that would mean increased benefits from ACS. About 150 new members are needed this year to achieve our goal (about a 5% increase). One way to increase membership is to urge graduate students to join the ACS and the Division, at least while they are still students. The cost of membership for students is low and the benefits are significant. It is our hope that students who join will find membership sufficiently advantageous to continue their association with the Division and ACS after graduation. Some members of the Committee, who have unrestricted funds available to them, are planning to pay for their graduate students' member dues while they are still degree candidates. (The cost for students is presently $47.50/year to join both the ACS and the Division.) Whether or not this option is open to you, I ask that you urge your students to join both ACS and the Division of Physical Chemistry. The benefits for both our students and the Division are substantial! Instructions for joining the Division of Physical Chemistry are given elsewhere in this newsletter, and membership information/application forms may be obtained from the American Chemical Society [; 800-227-5558/202-872-4567; FAX 202-872-6337].

The second item of importance considered by the Executive Committee in San Francisco concerns our "Travel Fellowship" program. At each ACS National Meeting we provide a small stipend to defray travel expenses for a number of graduate students who give papers (usually posters) at the meeting. This is a very popular program, but rather small. The size is limited by our income from ACS each year, which is set by the number of attendees from the Division that attend the National Meeting, the number of papers given, etc. To increase the size of this Travel Fellowship program, the Executive Committee has agreed to match on a one for one basis (up to $15,000) any gifts the Division receives. This money will be used to create an "endowment" of roughly $30,000. The yearly income from this endowment will be used to finance an increase in the number of Fellowships awarded each year or their size, as determined appropriate by the Program Chair, who administers this program. We estimate that this modest endowment will allow us to increase the size of the Travel Fellowship program by about 50%. Donors willing to provide $5,000 in matching funds will have the opportunity to name a Travel Fellowship after their company or organization. If you are a potential donor or know of any organization that might be interested in supporting this program, please contact me or my successor as Division Chair, Ellen Stechel.

Remember that the Physical Division has two vigorous subdivisions for theoretical and biophysical chemistry. Membership in the subdivisions is free for anyone who is already a member of the Division of Physical Chemistry. For further information about the subdivisions contact the respective Secretaries, Mike Page (theoretical subdivision) or Gerald Babcock (biophysical subdivision).

Please note that the Las Vegas Meeting starts on Sunday night due to arrangements the ACS has made with the City of Las Vegas. This will result in a noticeably shortened meeting for September. I urge you to come to Las Vegas and to sample the rich offering of scientific symposia put together for you by Physical Chemistry Division Program Chair Ellen Stechel!

Remember that the Division maintains a Web site now due to the good offices of Mark Gordon and Steve Bachrach. Come and visit us on the world wide web at!

I would like to take this opportunity to thank all the members of the Executive Committee who have been of great assistance during my tenure as both Chair and Program Chair of the Division. Past Chairs Paul Barbara and Mark Ratner set examples for energy, organization, and effort that have been a challenge to match. Special thanks goes to my three successors in this position, Ellen Stechel, Geraldine Richmond, and George Schatz both for their superb efforts in behalf of the Division and their willingness to serve. I cannot overemphasize how important and well filled the position of Secretary-Treasurer has been under both Mark Gordon and Andrew DePristo during the past four years. Mark and Andrew have provided the continuity to the Executive Committee that is crucial to the functioning of the Division. Finally, no organization can run without the kind of truly superb, professional administrative help provided by Nancy Anderson and Kris Hinders in Iowa. I thank all of these people for their help and good humor and for a job well done!

Remarks by the Physical Division Program Chair

Ellen B. Stechel

As we approach the Fall ACS 1997 National Meeting, it is worth reflecting back on the Spring Meeting in San Francisco. I have received numerous letters and emails of congratulations and containing positive feedback. By all accounts I believe it is fair to declare the meeting very successful. While I would dearly love to take credit for that success, I sincerely hope the same encouraging words were expressed to the people that really make a meeting successful, the symposium organizers. Unquestionably they did a great job and I sincerely hope that you appreciate, as I do, their efforts. I also hope that they are gratified with the fruits of their labor. I certainly am!

So please join me in congratulating and thanking, W.E. Moerner & Sunney Xie (Chemistry of Single Molecules); Rod Bartlett & Martin Head-Gordon (Frontiers in Electronic Structure Theory); Stanley Williams & Bob Hwang (Kinetics of Growth on Surfaces); Martin Moskovits, Vladimir Shalaev & Paul Alivasatos (Nanostructured Materials: Clusters, Composites & Thin Films); John Yates & Hannes Jonnson (New Concepts in Surface Science: Surface Diffusion) and Roger Miller & Peter Felker (Orientational Effects in Chemical Reactions). The sustained audiences from the first talk Sunday morning to the concluding talks on Thursday were more than I could have hoped for and clearly demonstrated the excellence of the programs planned by these organizers.

I look forward to seeing many of you in Las Vegas where I believe the symposium organizers again did a superb job putting together a vibrant and exciting program. If you enjoy the sessions please tell the people that are responsible, the symposium organizers.

Notes from the Secretary-Treasurer

Mark Gordon

This newsletter contains information about the ACS national meetings and any other items of interest to significant numbers of PHYS division members. All members of the PHYS division are welcome to submit items to the Secretary for inclusion in the newsletter. The deadlines are generally around December 1 and May 1 for the newsletters appearing before the Spring and Fall ACS meetings, respectively. Submissions may be made via mail, FAX or e-mail.

Election Information

Dear PHYS Division Member:

Attached you will find approval ballots for the positions of Councilor and Alternate Councilor as required by ACS bylaws. These positions are for the years indicated on the ballot. Brief biographical material for all the candidates is also attached for your information.

The Bylaws of the Division of Physical Chemistry, approved in 1977, call for the Division Chair to appoint a three person nominating committee before the spring meeting. A complete slate of candidates prepared by this committee will consist of one candidate for Vice-Chair-Elect, one candidate for each of two vacancies on the Executive Committee, and one candidate for each vacancy that may have developed in the ranks of the division Councilors, Alternate Councilors, and Secretary-Treasurer position. The Vice-Chair-Elect automatically becomes the Vice-Chair, Chair-Elect, Chair, and Immediate Past-Chair in each succeeding year. Thus this person makes a commitment to serve five years on the Executive Committee. In the year this person serves as Chair-Elect the duties of Program Chair are also his or hers. The term of office for other Executive Committee members, Councilors, and Alternate Councilors is three years. The Secretary-Treasurer serves five years.

The Secretary-Treasurer is required to announce the slate of candidates in the fall newsletter (which is part of the abstract separates for the fall meeting).

To increase the input of the members in this nominating process and to broaden the pool of candidates, the executive committee seeks input directly from members for use by the nominating committee. Any member may suggest nominees to any of the officers of the PHYS division in writing. The nominee must agree to serve.

Additional nominations can come from the membership in the following fashion: A petition candidate must be supported by the signatures of not fewer than 4% of the members of the PHYS division in good standing (presently approximately 3,300). No signature shall be valid if it appears on more than one nominating petition for the same vacancy during the same calendar year.

A letter shall be submitted from each petition nominee stating willingness to be a candidate for election and to serve the Division for a full term if elected. No nominee may be a candidate for more than one vacancy. If nominated for more than one vacancy, the nominee must choose which nomination to accept.

Four weeks from the date of the mailing of the fall newsletter shall be allowed for additional nominations to be received by the Secretary-Treasurer. All valid nominations received within that period shall be accepted, and no others.

If no valid nominations are forthcoming from the membership, the nominees submitted by the Nominating Committee for Vice-Chair-Elect, Secretary-Treasurer and membership on the Executive Committee are declared elected.

Regardless of whether petition nominees are validated or not, the Bylaws require the Secretary-Treasurer to mail to every PHYS division member a ballot that bears at a minimum the names and biographical sketches of the single candidates for each Councilor and Alternate Councilor vacancy submitted by the Nominating Committee.

This year the Nominating Committee consisted of Mark Ratner, Laurie Butler and David Dixon. They submitted the following slate of candidates:

Biographical sketches of all the nominees follow. A ballot for the Councilor and Alternate Councilor positions is included immediately thereafter on a tear-out page.

Restrictions on Speakers for PHYS Symposiums

A speaker may give, at most, one invited talk in the PHYS division in any one calendar year. Note that these rules do not apply to contributed talks and posters, so there is still plenty of opportunity for all physical chemists to present their research results in the PHYS division.

Request for Symposia Topics and Speakers

The Executive Committee has been soliciting formal suggestions for symposia and speakers for the meetings to be held in three years. These suggestions will be essential input for organizing the programs of the meetings. For greatest effectiveness, follow these suggestions:

Numerous symposiums in 1999 have been accepted based upon these suggestions.

The deadline for receipt of suggestions is February 1, 1998. (Address these to the Secretary/Treasurer, Mark S. Gordon, at the address in the table of officers.) The Executive Committee will meet in Dallas in March to plan the programs for 2000.

Autumn Meeting

Technical Program

The 214th American Chemical Society National Meeting will take place in Las Vegas, NV during the week of Sept. 7-11, 1997. The National meeting typically begins Sunday morning and ends Thursday afternoon. However, the 214th will begin Sunday evening, Sept. 7, at 8pm with the division's first of two poster sessions. Dr. Ellen B. Stechel, 1997 Physical Chemistry Division Program Chair, has arranged a technical program consisting of six topical symposia, two general poster sessions and a town meeting with the National Science Foundation. The second poster session will be Wednesday evening at 7pm and the town meeting will be Tuesday evening at 5pm. The divisions of Analytical and Colloid & Surface Chemistry will be co-hosting the town meeting. Refreshments will be served. The organizers, Janet Osteryoung (NSF) and W. Carl Lineberger (U. of Colorado, Boulder), will focus the open discussion to encompass issues that are currently facing the basic research community and its sponsors, such as the NSF. Topics of special interest are the academic infrastructure for research and funding priorities during a period of constrained budgets. Travel plans permitting, NSF Chemistry Division program officers will attend.

The topical symposia and their organizers are:

The individual symposium organizers of each of the topical symposia have put together compelling symposia by inviting speakers and selecting additional speakers from contributed presentations. The selected contributions come from those that specifically request an oral presentation in their symposium. The criterion for selection is a close connection with the topics addressed in the symposium. Since the symposium organizers are unable to accommodate all requests, the poster sessions are specifically organized to group posters by symposium topic. While the topical symposia do cover a wide range of topics, they cannot cover the full depth or breadth of physical chemistry. The division welcomes general contributions to the poster sessions; these are grouped by subject area. Some highlights from each of the topical symposia follow.

The symposium on Biophysical Chemistry emphasizes magnetic resonance of biological systems ¾ solution and solid state NMR, high field and pulsed EPR, etc. Additional sessions will cover scanning microscopy and other diverse approaches to biophysical chemistry. This symposium will run all week with posters on Wednesday evening.

The symposium on Dynamics in Molecular Systems features seven sessions on molecular dynamics in many different contexts, including isolated molecules, ions, charged/neutral clusters, surface-bound species, and in the condensed phase. In isolated molecules and ions, the dynamics of photodissociation, state-mixing, reaction, and coherent control will be highlighted. The unique intermolecular dynamics of finite-size molecular and ionic clusters will also receive attention, as will the dynamics of molecules colliding with or residing on surfaces and in solids. Symposium posters will be on Sunday evening. The first oral session is Monday morning and the last is Thursday afternoon.

The symposium on Homogeneous and Heterogeneous Processes in Atmospheric Chemistry covers laboratory, field and theoretical studies of atmospheric chemistry. It features a broad range of topics including: gas phase composition and reaction kinetics, ice and acid chemistry, particle formation and composition, toxic compounds in the troposphere, chemistry of sea salt particulates, and chemistry on surfaces of metal oxides and soot." This symposium is co-organized with the Division of Colloid and Surface Chemistry and will be running in both Divisions. In other words, the presentations are distributed between the two divisional programs. The first half of the symposium (Monday and Tuesday) will be in Colloids & Surface Chemistry. The second half (Wednesday and Thursday) will be in the Physical Chemistry. The symposium poster session will be Tuesday evening in the Division of Colloids & Surface Chemistry. For the purposes of the program, it will look like this is two symposia with the same name, one in each division. For the purposes of the attendee, this is just one symposium.

The symposium on Radiation Chemistry addresses broadly, in five oral sessions, the physical chemistry associated with the interaction of ionizing radiation with condensed matter. Sessions will include both fundamental mechanistic issues that underlie the observed chemistry and application to practical chemical problems. Symposium posters will be on Sunday evening and the oral presentations begin Monday morning and conclude with the Wednesday morning session.

The symposium on Structure and Dynamics at Liquid Interfaces will focus, in six sessions, on recent experimental and theoretical advances in the study of equilibrium and dynamics phenomena at liquid interfaces. The fundamental goal is to understand at the molecular level how the unique interfacial region affects chemical reactions, charge transfer, adsorption and solvation that take place at the interface. Symposium posters will be on Wednesday evening. The oral presentations will begin Monday morning. The concluding oral session will be Thursday morning.

The symposium on Self-Assembling Thin Film Materials is sponsored by the Materials Secretariat. Secretariats in the ACS are cross-divisional programming units. The Materials Secretariat programs one symposium at the Fall National Meeting. This year four divisions, ANAL (Analytic), COLL (Colloid & Surface Chemistry), BIOT (Biotechnology) and PHYS (Physical) have contributed to the symposium. The Division of Physical Chemistry will be hosting, on Wednesday evening, an extensive poster session for the full symposium on Self-Assembling Thin Film Materials. The topical sessions organized by the division of physical chemistry are Organized Multilayered Systems and Nanoscale & Patterned Assemblies. The session on Organized Multilayered Systems emphasizes recent advances in preparation, characterization, and applications of organized multi-layered systems including supported thin films and three-dimensionally organized materials. The session on Nanoscale & Patterned Assemblies focuses on using self-assembly techniques to produce nanoscale features and patterns on surfaces. Topical areas sponsored by ANAL, COLL or BIOT include: Techniques, Biomolecular Assemblies, Molecular Organization, and Applications.

Very Important Notice

They must also submit a copy of the abstract to the organizer of the symposium in which they wish to make their presentation. They should also get their abstract in one week prior to the deadline.

General Information For Contributed Papers

General Papers-Members are cordially invited to present papers at the poster sessions. Titles of papers and names of authors, with a short abstract, should reach the Chair-Elect (or Program Chair) by the deadline dates published in the Newsletter and in Chemical and Engineering News. The deadline must be observed to allow the ACS to compile the program and to print and to circulate the abstracts.

Classification By Subject Area-Authors are asked please to list on the bottom of the short abstract form (under the heading subject area) those of the following areas with which they prefer to see their poster papers classified or they can list a specific topical symposium that is part of the program.

Chemical Equilibrium Magnetic Resonance Solutions
Electrochemistry Photochemistry Spectroscopy
Kinetics: Gas Phase Theoretical Chemistry Thermodynamics
Kinetics: Liquid Phase Radiation Chemistry Others - Specify area

Short Abstract-The abstract must be sent on an ACS abstract form to the person who is Chair-Elect for the year of the meeting. The abstract form is typically available in academic chemistry department offices. They can also be downloaded from the Web; the appropriate page can easily be reached from the PHYS homepage

Forms can also be obtained directly from ACS at 1-800-227-5558, the general ACS number, select '4' for meetings, or 202-872-4396 (the direct meeting's number). In the unlikely event that neither of these have forms, contact the Secretary-Treasurer of the PHYS, Dr. Mark Gordon. The abstract cannot be changed in any way after the deadline date. It should arouse interest in the paper and do it justice. Succinctly state the purpose of the paper and mention important results and conclusions. Since the abstract is reproduced photographically, it is very important to use a good typewriter ribbon or laser printer cartridge. If the abstract has to be retyped, the Division of Physical Chemistry is required to pay for typing, which in the past this has been a sizable charge against the Division.

Information And Rules Applying to All Contributed Poster Papers

  1. No paper will be accepted unless an author expects to be present.
  2. ACS Bylaws 3(a) require that "papers by American Chemists or chemical engineers not members of the Society shall not appear on the program unless they be joint with one or more Society members."
  3. Prospective poster presenters who also submit papers to other Divisions should inform the Chair-Elect as to the Division, titles of papers and co-authors by the deadline date.
  4. Each poster paper will have a poster board measuring 4'x8'.
  5. All illustrations, charts, and textual material to be posted must be prepared in advance since materials for these purposes will not be available at the meeting.
  6. Posters should be mounted prior to the opening of the session and left in place until the close. Authors are encouraged to be present the entire session.
  7. There must be a heading (with lettering at least 1½" height) giving the title of the papers, the author(s), their affiliation(s), and the number assigned to it in the program.
  8. Illustrative material will be read by attendees from a distance of 3' or more, so lettering on illustrations should be at least 3/8" high.
  9. There should be a logical sequence (introduction, development and conclusion) to the display and each sheet should be numbered.
  10. The presentation's effectiveness will be enhanced by mounting the sheets on colored construction paper and using other techniques for improving graphic impact. Ease of reading is far more important than artistic flair. Certain color combinations, for instance, may look beautiful but be almost impossible to read, especially in the absence of optimum lighting.
  11. Do NOT mount illustrations on heavy stock which is difficult to mount on the poster boards.
  12. Each author is responsible for mounting his or her material at least 1/2 hour prior to the opening of the assigned poster session and removing it within 1/2 hour after the close of the session. ACS cannot assume any responsibility for materials beyond those time limits.
  13. Do provide sign-up sheets to record names and addresses of attendees who wish more information.
  14. Do bring duplicates of data and conclusions. Duplicating facilities are unavailable through ACS.
  15. ACS provides a modest supply of push-pins, masking tape and felt-tipped pens but it is wise to bring your own. Upon advance request, ACS will arrange for blackboards to be available in the room.
  16. Admission to poster sessions will be by ACS meeting badge only.
  17. A poster paper submitted to the Program Chair (before the deadline) for presentation at a national meeting should be considered accepted unless the author is specifically notified to the contrary by the Division of Physical Chemistry Program Chair.

Did You Know?

Many physical chemists are not members of the ACS and are not aware of the fact that they can become Affiliates of the Division of Physical Chemistry and the Subdivisions of Theoretical and Biophysical Chemistry without being a member of the ACS itself. At $10.00 per year, the dues for Affiliates are slightly higher than for Members, but many of the advantages of association with the Division are the same. (Division Affiliates may not hold elective office and may not vote in Division elections.) Because it is expensive to make extensive mailings to non-ACS members, we request your assistance in publicizing this option. Please inform your colleagues of this information and share the application on the last page of this newsletter with anyone who may be interested in becoming an Affiliate of the Division.

American Chemical Society

Division of Physical Chemistry

Subdivision of Theoretical Chemistry

Subdivision of Biophysical Chemistry

We invite you to encourage non-members to join the PHYS division. It is the professional organization devoted to physical chemistry and physical chemists and can be most successful with maximum participation by physical chemists. Some of the more practical advantages of membership are:

1. Members receive, in advance, abstracts of the papers to be delivered in the Division of Physical Chemistry programs at national meetings of the ACS.

2. Members receive a newsletter with the abstracts of the National meetings listing future symposia and divisional meetings, and giving the deadlines for submission of papers to be presented at these meetings. The newsletter is included with the abstracts of papers for convenience.

3. Members receive discounts on the purchase price of the complete bound books of meeting abstracts. Discounts for other books and journals are also available, and new arrangements are negotiated from time to time.

4. The Division of Physical Chemistry is an affiliate of the American Institute of Physics, and members of the Division are eligible for a discount on various AIP publications including The Journal of Chemical Physics.

5. The Division holds mixers at each national meeting of the ACS at which a divisional program is presented. These events are held in conjunction with a poster session and provide an excellent opportunity to meet other physical chemists.

6. Members may vote and hold office in the Division and participate in its activities. Division Affiliates may not vote and may not hold office. Members and Affiliates are invited to suggest symposium topics, speakers and organizers.

7. The Division maintains a close relationship with the Journal of Physical Chemistry. Through the Division programs, and through cooperation with the Journal of Physical Chemistry, we seek to call attention to the vigorous and dynamic character of physical chemistry in this country, and to stimulate intellectual cross-fertilization between the different fields of research in physical chemistry.

8. The Division mounts important award symposia. The Debye, Hildebrand and Theoretical Chemistry awards are given each year, and the Langmuir Award every other year by the ACS. In addition, the Pure Chemistry and Nobel Laureate Signature awards are frequent features in Division symposia.

10. In 1978 the Division established the Subdivision of Theoretical Chemistry. There is no additional fee for membership in the Subdivision. The Subdivision provides special services and participates fully in developing symposium topics, at the national meetings, specifically for the theoretically inclined.

12. In 1994 the Division established the Subdivision of Biophysical Chemistry. There is no additional fee for membership in the Subdivision. The Subdivision provides special services and participates fully in developing symposium topics, at the national meetings, specifically for the biophysically inclined.
