Laser Spectroscopy Probing of Excitation and Coherence Dynamics

为了继续他们在激光光谱学探测激发和相干过程方面的努力，他们建议利用这笔续期拨款在以下领域进行研究：(A)凝聚介质中模型系统中电子和激发转移的超短时间动力学；(B)用于研究相干和驰豫过程的选择性脉冲激发；(C)微观溶剂化和团簇的激光光谱学研究。他们将在这项研究中使用的技术(已经在他们的实验室中使用)是皮秒和飞秒光谱、多脉冲光激发方法和多光子(TOF和PES)探测方法。他们的目标是应用(和修改)这些技术来了解凝聚介质中能量松弛、溶剂化和相干性的动力学，并检查经历(微观)溶剂化和团簇形成的分子的皮秒和飞秒动力学。

In continuation of their efforts on laser spectroscopy probing of excitation and coherence processes, they propose to use this renewal grant to undertake research in the following areas: (a) ultrashort time dynamics of electron and excitation transfer in model systems in condensed media; (b) selective-pulse excitation for the invesitgation of coherence and relaxation processes; and (c) laser spectroscopy studies of microscopic solvation and clustering. The techniques that they shall use in this research (which are already used in their laboratory) are picosecond and femtosecond spectroscopy, multiple pulse optical excitation methods, and multiphoton (TOF and PES) detection methods. Their objectives are to apply (and modify) these techniques to learn about the dynamics of energy relaxation, solvation, and coherence in condensed media, and to examine the picosecond and femtosecond dynamics of molecules undergoing (microscopic) solvation and clustering formation.
