A Time-Resolved Spectrometer Based on a Titanium: Sapphire Laser

化学研究仪器和设施(CRIF)计划和主要研究仪器(MRI)计划颁发的这一奖项将使佛罗里达州立大学化学系能够获得基于钛：蓝宝石激光的时间分辨光谱仪。该系统将提供更高的时间分辨率、更宽的样品激发波长范围以及记录到紫外线中的瞬时吸收光谱的新能力。研究将集中在凝聚相研究，包括a)探测溶液中有机分子的光诱导现象；b)复杂分子系统中的激发动力学；c)探测飞秒时间域中的光化学反应机理；d)金属/二氧化硅固体中的光物理和光化学过程。激光系统是一种非常通用的光谱仪，可以用来完成大量的光物理和光化学研究。教员们将能够探索极其基本的过程，这些研究将产生以前无法获得的信息。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program and the Major Research Instrumentation (MRI) Program will enable the Department of Chemistry at Florida State University to acquire a time-resolved spectrometer based on a titanium:sapphire laser. This system will provide new capabilities for greater time resolution, a wide range of sample excitation wavelengths, and the recording of transient absorption spectra into the ultraviolet. Research will focus on condensed phase studies, including a) probing photoinduced phenomena in organic molecules in solution; b) excitation dynamics in complex molecular systems; c) probing photochemical reaction mechanisms in the femtosecond time domain; and d) photophysical and photochemical processes in metal/silica solids. The laser system is an extremely versatile spectrometer that can be used to accomplish numerous photophysical and photochemical studies. The faculty will be able to probe extremely fundamental processes, and these studies will yield information not previously attainable.
