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

这份来自化学研究仪器和设施（CRIF）项目和主要研究仪器（MRI）项目的合同将使佛罗里达州立大学化学系获得基于钛蓝宝石激光器的时间分辨光谱仪。该系统将提供更高的时间分辨率，更宽范围的样品激发波长，以及记录瞬态吸收光谱到紫外线的新功能。研究将集中于凝聚相研究，包括a)探测溶液中有机分子的光致现象；B)复杂分子体系的激发动力学；C)在飞秒时域探索光化学反应机制；d)金属/硅固体中的光物理和光化学过程。激光系统是一个非常多功能的光谱仪，可用于完成许多光物理和光化学研究。教师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.
