With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Arizona State University will acquire an instrument for ultrafast fluorescence and multipulse transient absorbance. Research will focus on a) artificial photosynthesis, such as studies of biomimetic reaction centers coupled to artificial antenna systems; b) oxidative damage in DNA; c) redirecting electron transfer in photosynthetic reaction centers of purple nonsulfur bacteria; and d) ultrafast spectroscopic studies on photosynthetic pigments, antennas and reaction centers. 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, in particular biochemistry.

在化学研究仪器和设施(CRIF)计划的支持下，亚利桑那州立大学化学系将获得一台用于超快荧光和多脉冲瞬时吸收的仪器。研究将集中在a)人工光合作用，如与人工天线系统耦合的仿生反应中心的研究；b)DNA的氧化损伤；c)紫色非硫细菌光合作用反应中心的电子转移；以及d)光合色素、天线和反应中心的超快光谱研究。瞬变吸收光谱是一种非常通用的工具，可以用来探测基本的光物理和光化学过程。这些研究将在许多领域产生影响，特别是生物化学。
