Chemical Bonding Theory – Perspectives from Valence Bond (VB) Related Theories
Most fundamental concepts in chemistry originate from the early qualitative valence bond (VB) theory, including bond pairs, lone pairs, hybrid orbitals, and resonance. However, the computational complexity involving the non-orthogonality of the orbitals in VB theory hindered its further development and over the years MO theory (including DFT) has become synonymous with computational chemistry. During the past two to three decades, there has been a remarkable renaissance in modern ab initio VB or similar methods along with critical computer software developments and distributions. The broad applications of these VB methodologies have generated novel insights into the nature of chemical bonding and reaction mechanisms and enriched our understanding of chemistry. Thus, VB methods complement the popular MO/DFT methods in a multitude of ways. Considering the recent remarkable advances in VB theory and its applications, we have organized a symposium that will highlight the work of the major players in the VB field, as well as leading experts in electronic structure and chemical bonding theories, who will showcase their research findings, create consensus from different perspectives, and, finally, draw advancements in VB theories to the attention of the whole chemistry community. The organizers welcome other submissions that contribute to these themes.

Marine Aerosols in the Atmosphere and Their Impacts
Sea spray aerosol particles (SSA), formed through wave breaking at the ocean surface, contribute to natural aerosol particle concentrations in remote regions of Earth’s atmosphere and alter the direct and indirect effects of aerosol particles on Earth’s radiation budget. The proposed symposium will focus on how physical chemistry plays a key role in understanding these global impacts. The symposium will be co-organized by researchers and leaders within the National Science Foundation (NSF) Center for Aerosol Impacts on Chemistry of the Environment. As one of the NSF Centers for Chemical Innovation (CCI), CAICE tackles the grand challenge of elucidating how the chemical complexity of atmospheric aerosol particles impacts our atmosphere and climate. SSA has tremendous chemical variability depending on ocean chemistry, biology, and physical factors such as waves and wind. CAICE has established a unique ocean-atmosphere interaction facility that replicates natural sea spray aerosol in a controlled setting, allowing for detailed fundamental physical chemistry studies of aerosol reactions in both complex “top-down” and building the complexity “bottom-up” approaches. A hallmark of this research has been the tight coupling of theory and experiment. Outreach and educational activities have also played a key role in getting K-12 students and the public excited about environmental and physical chemistry. This symposium celebrates the exciting and fruitful 13 years as this chapter of the NSF CCI comes to a close.

Chemistry and Properties of Two-Dimensional Materials
Two-dimensional (2D) materials have spawned a new frontier in chemistry and materials research. While graphene was the primary focus of study in the early days of 2D materials research, today many new classes of 2D materials have captivated the interest of physicists, chemists, engineers, and materials scientists. In order to provide a comprehensive and critical perspective on the status of 2D materials, this symposium aims to (i) highlight emerging research, (ii) cultivate a diverse community of scholars, and (iii) provide a roadmap for future research opportunities. Talks in this symposium cover elemental 2D materials beyond graphene (e.g., phosphorene, borophene, silicene), compound 2D materials (e.g., transition metal chalcogenides), layered metal oxides and halides, organic-inorganic metal halide layered perovskites, 2D molecular frameworks, and their heterostructures, including moire superlattices. The symposium welcomes submissions that focus on the synthesis, fundamental properties, device physics studies, and applications of these materials, for example in quantum information, sensing, optics, and energy conversion. Contributions focused on development of methods for controlled growth of 2D materials and on advanced spectroscopy and microscopy techniques are of particular interest. Bringing together researchers with complementary expertise in advanced spectroscopy, microscopy, synthesis, device fabrication, and application of 2D materials promises to open new frontiers for 2D materials in the world of chemistry.

Quantum Computing for Tackling Challenges in Quantum Chemistry
Quantum computing is a fundamentally new paradigm for computation and information processing made possible by harnessing physical phenomena unique to quantum mechanics. Chemistry is one of the most promising applications of quantum computing. While the current noisy near-term quantum computing systems fall short of the requirements for fault-tolerant systems, they provide unique opportunities for novel quantum applications in chemistry. This symposium will bring together a diverse community of scientists from industry, academia, and government to identify challenges in chemistry simulations with classical computers and share the newest developments and solutions brought by quantum computers.

Data-Driven Design of Energy Materials
The past years have been marked by fast-paced advances in the data-driven and Machine Learning (ML)-aided design and characterization of energy materials. Equally remarkable is the broad range of theoretical methods, physical systems, and applications that ML-aided research has enabled to explore. Recent advances in the field include the design of high-performance materials for energy storage, the modeling of catalysts for renewable energy, combinatorial approaches for ceramic fuel cells, combined quantum mechanical-ML approaches for electrochemical systems, and the design of novel nanoporous materials for hydrogen capture, among others. This symposium will bring together chemists, physicists, and engineers from these different areas, with complementary computational and experimental expertise, to share the cutting-edge advances in the design of energy materials enabled by ML in their respective fields. We anticipate that the symposium will enable participants to explore how recent methodological developments can be transferred from one area to another, and, in turn, accelerate discovery and address outstanding challenges in energy materials research.

The Astrochemistry Subdivision: A Decade of Progress and Prospects for the Next Decade
The Astrochemistry Subdivision convened its first symposium 10 years ago during the Fall 2013 national meeting. It has been a decade of immense progress for the field of astrochemistry, and many members of the Subdivision have made seminal contributions to the field. The astronomical detection of new molecules has exploded in recent years with the Atacama Large Millimeter Array (ALMA) and large single-dish observatories (e.g., GBT, IRAM 30m) leading the way. 2021 alone saw announcements for the detection of over 30 new molecules, far more than the annual averages from the previous years. The James Webb Space Telescope has already sent back stunning imagery of the cosmos. All observations are founded upon critical experimental and theoretical chemistry contributions, which provide a steady stream of data and predictions. Observation, experiment, and theory all complement each other enormously. As a symposium that looks both back over the accomplishments of the last decade and forward toward the prospects of the next decade, we will encourage our speakers to share their dreams and ambitions for what might be learned in the years to come.

Intersections of Climate, Urban Living, and Chemistry
The Earth is warming. Patterns of rainfall are changing. Urban life is becoming increasingly electrified. As a result of these three intersecting trends there are profound changes occurring in the atmospheric composition of cities. For example, emissions from restaurants, household cleaning solvents, and urban trees are overtaking emissions from vehicles as one of the dominant factors contributing to poor air quality. Many of these emissions are strongly temperature dependent, making air quality especially poor on the hottest days. In addition, as emissions decrease, disparities in exposure to poor air quality that reflect land use policy are becoming more evident. In this symposium, we invite contributions that address this changing landscape, including laboratory and field based observational studies, evaluation of mechanisms and assessment and prediction with numerical models.
