Ultrafast Nonlinear and Coherent Spectroscopic Studies of Molecular Motion in Liquids

在这个实验物理化学计划（化学 司）项目，马克贝格教授（得克萨斯大学， Austin）将使用皮秒激光技术（时间分辨 空穴燃烧和拉曼回波）来研究溶剂的动力学 与反应中的非极性溶质分子的相互作用 液体.溶剂化对电子和振动的影响 状态，溶质附近的局部扩散运动，溶质-溶剂 热能转移和相关的溶剂运动将是 研究了 %%% 贝格教授将使用超快激光脉冲直接 观察溶剂对液体中化学反应的影响。 作为这项研究的一部分开发的新方法很重要 因为它们可以应用于更广泛的反应类型 比以前可能的。

In this Experimental Physical Chemistry program (Chemistry Division) project, Professor Mark Berg (University of Texas, Austin) will use picosecond laser techniques (time resolved hole burning and Raman echoes) to study the dynamics of solvent interactions with reacting, non-polar solute molecules in liquids. Effects of solvation on electron and vibrational states, local diffusional motion near solutes, solute-solvent thermal energy transfer, and correlated solvent motion will be studied. %%% Professor Berg will use ultra fast laser pulses to directly observe effects of solvent on chemical reactions in liquids. The new methods developed as part of this study are important because they can be applied to a much wider class of reactions than was possible previously.
