Purchase of a Departmental Nanosecond Transient Absorption Spectrometer

在化学研究仪器和设施（CRIF）项目的支持下，位于塔斯卡卢萨的阿拉巴马大学化学系将获得一台纳秒瞬态吸收光谱仪。研究将集中于光致电子转移研究，包括a)氧化还原梯度树状大分子中电子转移速率的测量；b)利用快速光谱法了解光系统I中叶绿醌辅助因子；c)用于光数据存储的新型发色团的光化学研究。瞬态吸收光谱是一种非常通用的工具，可用于探测基本的光物理和光化学过程。这些研究将对包括材料科学和生物化学在内的许多领域产生影响。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Alabama in Tuscaloosa will acquire a nanosecond transient absorption spectrometer. Research will focus on photoinduced electron transfer studies, including a) measurement of electron transfer rates in redox-gradient dendrimers; b) use of fast spectroscopy to understand the phylloquinone cofactor in Photosystem I; and c) investigations of photochemistry in novel chromophores for optical data storage. Transient absorption spectroscopy is an extremely versatile tool that can be used to probe fundamental photophysical and photochemical processes. These studies will have an impact in a number of areas including materials science and biochemistry.
