With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at SUNY College at Buffalo will acquire a Step-scan Time-resolved FTIR and pulsed Nd-YAG Pump Laser for Studies of Photo-induced Species in Chemical and Biomolecular Systems. The proposed instrumentation will be used to: 1) complement on-going time-resolved x-ray crystallographic studies aimed at elucidating geometrical changes that accompany the formation of short-lived photo-excited states; 2) elucidate changes that occur in the active site and surrounding protein during the activation and splitting of hydrogen by the hydrogenases; 3) study the nature of differences in activation of calmodulin in its native form compared to calmodulin embedded in xerogels; 4) characterize electron transfer processes occurring at semiconductor nanomaterial surfaces; 5) integrate time resolved infrared studies on the photochemistry of metal nitrosyls and metal carbonyls into the undergraduate curriculum. Faculty at SUNY in Buffalo will share access to this equipment These studies will have an impact in a number of areas, including biochemistry, nanoscience and materials science.

在主要的研究仪器（MRI）计划的支持下，布法罗纽约大学的化学系将获得一阶扫描时间分辨的FTIR和脉冲ND-YAG泵激光，以研究化学和生物分子系统中光诱导的物种。所提出的仪器将用于：1）补体持续分辨的X射线晶体学研究，旨在阐明伴随短暂的光兴奋状态形成的几何变化； 2）阐明在活性位点和周围蛋白质中发生的变化，并在氢化酶对氢的激活和分裂过程中发生变化； 3）研究与干凝胶中嵌入的钙调蛋白相比，研究钙调蛋白激活钙调蛋白激活的差异的性质； 4）表征在半导体纳米材料表面发生的电子传递过程； 5）将有关金属亚硝基和金属羰基光化学的时间分辨的红外研究整合到本科课程中。 布法罗纽约州立大学的教师将共享对该设备的访问权限，这些研究将在许多领域产生影响，包括生物化学，纳米科学和材料科学。
