Ultraviolet Resonance Raman Studies of Electronic Excitations

在化学学部物理化学项目中，Syracuse University的Bruce S. Hudson教授将继续并扩展一系列关于激发态电子的紫外共振拉曼光谱和小多原子分子动力学的研究。气相和液相系统都将被研究。将对溶液中的分子进行新的研究。这些研究包括结构溶剂化对氢键和介电性能的影响，归因于波动溶剂效应的静态和动态修饰，以及激发驱动的溶剂效应。还将研究使用液态氙、六氟化硫和四氟化碳作为溶剂的可行性。共振拉曼光谱提供了电子激发后原子运动的早期时间动力学的“快照”视图。从分子结构理论的观点来看，这种瞬时响应是有意义的。这些研究的总体目标是测试和完善激发态的理论描述。

In this project in the Physical Chemistry program of the Chemistry Division, Prof. Bruce S. Hudson of the Syracuse University will continue and extend a series of investigations on the ultravilolet resonance Raman spectroscopy of excited electronic states and dynamics of small polyatomic molecules. Both gas and liquid phase systems will be investigated. New investigations will be conducted on molecules in solution. These include studies of structural solvation effects on hydrogen bonding and dielectric properties, static and dynamic modifications attributed to fluctional solvent effects, and excitation driven solvent effects. The feasibility of using liquid xenon, sulphur hexafluoride, and carbon tetrafluoride as solvents will also be investigated. Resonance Raman spectroscopy provides a `snapshot` view of the very early time dynamics of atomic motions following electronic excitation. This instantaneous response is of interest from the point of view of molecular structure theory. The overall goal of these studies is to test and refine theoretical descriptions of excited electronic states.
