This research, in the Experimental Physical Chemistry Program, uses laser techniques to probe the spectroscopy, kinetics and dynamics of metal inorganic compexes on the femto-, nano- and picosecond time scales. Such studies are important to inorganic and biochemial processes. The dynamics of excited electronic states and photochemical reactions in transition metal compounds at short times in the subnanoseceond and femtosecond time scale will be investigated. This research will study charge transfer excitations, conformational relaxation of molecules following such processes, nonradiative transitions to lower lying states of various types, and solvent reorganization around solutes undergoing charge transfer transitions all of which require this time resolution.

本研究在实验物理化学项目中，使用激光技术在飞秒、纳米和皮秒时间尺度上探测金属无机化合物的光谱、动力学和动力学。这类研究对无机和生物化学过程具有重要意义。在亚纳秒和飞秒时间尺度下，研究过渡金属化合物短时间内的激发态和光化学反应动力学。本研究将研究电荷转移激发，分子在此过程中的构象弛豫，各种类型的低能级非辐射跃迁，以及发生电荷转移跃迁的溶质周围的溶剂重组，所有这些都需要这个时间分辨率。
