Chemical Dynamics of Polyatomic Molecules: New Probes for New Insights

Wayne州立大学的Arthur G. Suits教授和他的研究生、本科生和博士后研究人员正在研究重要小分子的物理和化学性质，该奖项由化学学部化学结构、动力学和机制（CSDM-A）项目资助。西服教授和他的团队工作的最终目标是更好地理解大气中重要分子或化学上有趣分子的反应性。从事该项目的年轻研究人员将从物理化学领域的一位领军人物那里接受最先进方法的培训。Suits和他的研究小组将利用受激多原子分子产生的自旋极化氢原子的成像来揭示包括水和甲烷在内的重要分子的光化学细节。这样的工作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小组将使用啁啾脉冲，均匀流动光谱仪来研究不稳定化学中间体的反应动力学，包括像HOONO这样的外来物种。本研究的目的是了解这些转瞬即逝的中间体在复杂的、现实世界的反应系统中所起的重要作用。

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.
