Ultraviolet Resonance Raman Studies of Dephasing Times in Solution (Chemistry)

迈尔斯博士虽然刚刚开始自己的研究，但她已经是这项研究领域公认的专家。她计划使用绝对共振拉曼强度和激发谱带来探索溶剂对激发态溶质能级和寿命的影响。这些研究在评价共振拉曼散射理论和帮助理解溶液效应方面都是重要的。Myers博士将测量一些小分子，如苯胺、氨、二硫化碳和碘化甲酯，在气相和常规溶剂和液化稀有气体溶液中的紫外共振拉曼激发谱、绝对横截面和去极化比。实验将利用绝对共振拉曼强度和激发谱带对溶剂诱导展宽机制的敏感性。这些结果将有助于评价溶液中的共振拉曼散射理论以及溶剂-溶质相互作用的动力学。

Dr. Myers, although just starting on her own is already a recognized expert on the subject of this research. She plans to use absolute resonance Raman intensities and excitation profile bandshapes to explore solvent effects on excited state solute energy levels and lifetimes. These studies are important both in evaluating theories of resonance Raman scattering and in helping to understand solution effects. Dr. Myers will measure the ultraviolet resonance Raman excitation profiles, absolute cross sections and depolarization ratios for several small molecules like aniline, ammonia, carbon disulfide, and methyl iodide in both the vapor phase and in solutions of both conventional solvents and liquefied rare gases. The experiments will exploit the sensitivity of absolute resonance Raman intensities and excitation profile bandshapes to solvent- induced broadening mechanisms. The results will aid in evaluating theories of resonance Raman scattering in solution as well as dynamics of solvent-solute interactions.
