The Chemical Structure, Dynamics and Mechanisms (CSDM) Programs support chemistry research that has strong implications for advancing the foundational knowledge of chemical systems.

The Program supports research on the nature of chemical structure, structure-property studies, thermodynamics and

kinetics, and mechanisms.

The CSDM Program is divided into two sub-programs, CSDM-A and CSDM-B.

The research supported by the two programs is distinguished in terms of whether their goal is to challenge thinking about physical phenomena in chemical systems through the development of innovative experimental approaches and new conceptual models (CSDM-A) or to use existing experimental methods and current conceptual frameworks to understand and describe physical processes in molecules and materials that are becoming increasingly relevant in modern applications (CSDM-B).

Projects supported by CSDM-A typically involve in-depth analysis of experimental data at the quantum- or statistical-mechanical level, often with an outcome being the modification or updating of the theoretical model.

Projects supported by CSDM-B also rely on theory to interpret structure-function relationships, but tend to focus on the consequence of structure (or changes in structure) on reactivity and other behaviors.

Projects involving nanochemistry or biologically-relevant systems should consult the Macromolecular, Supramolecular and Nanochemistry (MSN) or Chemistry of Life Processes (CLP) Programs, respectively.

Proposals for projects whose primary goal is the development of an entirely new instrumental technique, or enhanced performance or understanding of an existing technique may be more appropriate for the Chemical Measurement and Imaging (CMI) Program.

In general, research focused on solid-state chemical processes are not supported by CSDM.

Investigators interested in this area should consult with the Solid State Materials Chemistry (SSMC) Program in the Division of Materials Research (DMR).

Projects for which the primary goal is the development of a practical device are not supported by the CSDM-A and CSDM-B Programs and should be submitted to an appropriate program in the Engineering Directorate.

The following Program Descriptions are intended to guide the proposer to the most appropriate sub-program for her/his research.

CSDM-A:
The Chemical Structure, Dynamics and Mechanisms-A (CSDM-A) Program supports experimental and applied computational research directed at increasing our fundamental understanding of the physical properties of chemical systems at the quantum and/or statistical mechanical level.

Projects of interest to CSDM-A rely heavily on the advancement of sophisticated experimental techniques, such as:
state-selective methods, time and frequency domain spectroscopies, microscopies, single-molecule methods, scattering and diffraction approaches, and surface characterization techniques.

The program is interested in projects where the development of novel methods enables the physical behavior of chemical systems to be viewed in new ways, or in ways that challenge current paradigms.

Chemical systems studied range in complexity and include isolated molecules and ions, liquids, clusters, surfaces, and interfaces.

The CSDM-A Program also supports applied computational chemistry activities that demonstrate strong synergy with experiment.

Submissions that address national needs are particularly encouraged.

These may include, but are not limited to:
quantum chemistry where the focus in on the application of quantum mechanics in physical models and experiments of chemical systems.
