In this award, funded by the Chemical Structure, Dynamics and Mechanisms (CSDM-A) Program of the Division of Chemistry, Professor Arthur G. Suits of Wayne State University and his graduate student, undergraduate student and post-doctoral researcher colleagues are investigating the physical and chemical properties of important small molecules. The ultimate goal of the work by Professor Suits and his group is to develop a better understanding of the reactivity of atmospherically important or chemically interesting molecules. The young researchers working on this project will receive training in state-of-the art methods from a leader in the field of physical chemistry.Prof. Suits and his research group will use imaging of spin-polarized hydrogen atoms produced from excited polyatomic molecules to unravel the details of the photochemistry of important molecules, including water and methane. The results from work like this will help scientists understand the photochemistry of planetary atmospheres. In further experiments, the Suits Group will use a chirped-pulse, uniform flow spectrometer to study the reaction kinetics of unstable chemical intermediates, including exotic species like HOONO. The goal of this study is to understand the important role that these fleeting intermediates play in complex, real-world reacting systems.

在该奖项中，由化学系化学结构、动力学和机理（CSDM-A）项目资助，韦恩州立大学的 Arthur G. Suits 教授及其研究生、本科生和博士后研究员同事正在研究重要小分子的物理和化学性质。 Suits 教授和他的团队工作的最终目标是更好地了解大气中重要的或化学上有趣的分子的反应性。 从事该项目的年轻研究人员将接受物理化学领域领导者的最先进方法的培训。西茨和他的研究小组将利用激发多原子分子产生的自旋极化氢原子的成像来揭示重要分子（包括水和甲烷）的光化学细节。 此类工作的结果将帮助科学家了解行星大气的光化学。 在进一步的实验中，Suits Group 将使用啁啾脉冲均匀流谱仪来研究不稳定化学中间体的反应动力学，包括 HOONO 等外来物种。 这项研究的目的是了解这些短暂的中间体在复杂的现实反应系统中发挥的重要作用。
