Presidential Young Investigator/Time- and Frequency-domain Studies of Reaction Dynamics in Solution

实验物理化学计划正在支持迈尔斯教授开发和应用光学光谱方法，以研究各种快速光化学反应和探测凝聚相中的分子动力学。这项研究得到了总统青年研究员奖的支持。紫外共振拉曼光谱被用来测量溶剂引起的光谱展宽，并提取关于液体中发生的微观不同环境的范围以及这些环境相互转换的时间尺度的信息。还将获得有关激活的势垒穿越和电子传输的动态的信息。在皮秒和亚皮秒时间尺度上的互补泵浦-探测时间分辨实验将被用来研究激发系统在比共振拉曼探测器更长的时间尺度上的演化。

The Experimental Physical Chemistry Program is supporting Professor Myers in the development and application of optical spectroscopic methods for studying a variety of fast photochemical reactions and for probing molecular dynamics in condensed phases. This research is supported by a Presidential Young Investigator Award. Ultraviolet resonance Raman spectroscopy is being used to measure solvent-induced spectral broadening and extract information on the range of microscopically different environments that occur in liquids, as well as the time scales on which these environments interconvert. Information will also be obtained on the dynamics of activated barrier crossings and electron tranfers. Complementary pump-probe time-resolved experiments on the picosecond and subpicosecond time scales will be used to study evolution of excited systems on time scales longer than is accessible with the resonance Raman probe.
