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.

在化学研究仪器和设施（CRIF）计划的支持下，位于塔斯卡卢萨的亚拉巴马大学化学系将获得纳秒瞬态吸收光谱仪。 研究将侧重于光诱导电子转移研究，包括a）氧化还原梯度树枝状聚合物中电子转移速率的测量; B）使用快速光谱学了解光系统I中的叶绿醌辅因子;以及c）光学数据存储用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。 这些研究将在包括材料科学和生物化学在内的许多领域产生影响。
