迈尔斯博士，虽然刚刚开始对她自己已经是一个 他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轮廓 探索溶剂对激发态溶质的影响 能量水平和寿命。 这些研究在以下两个方面都很重要： 评价共振拉曼散射理论， 了解解决方案的效果。 迈尔斯博士会测量紫外共振拉曼激发 剖面、绝对截面和退偏振比 几种小分子如苯胺氨二硫化碳 和碘甲烷的气相和溶液 常规溶剂和液化稀有气体。 的 实验将利用绝对共振的灵敏度 拉曼强度和激发轮廓带形溶剂- 诱导增宽机制。 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.
