Acquisition of a Step-scan Time-resolved FTIR and pulsed Nd-YAG Pump Laser for Studies of Photo-induced Species in Chemical and Biomolecular Systems

在主要研究仪器（MRI）计划的支持下，位于布法罗的SUNY学院化学系将获得步进扫描时间分辨FTIR和脉冲Nd-YAG泵浦激光器，用于化学和生物分子系统中光致物种的研究。拟议的仪器将用于：1）补充正在进行的时间分辨X射线晶体学研究，旨在阐明伴随着短寿命光激发态形成的几何变化; 2）阐明在氢化酶激活和裂解氢的过程中活性位点和周围蛋白质中发生的变化; 3）研究天然形式的钙调蛋白与嵌入干凝胶中的钙调蛋白相比的活化差异的性质; 4）表征在半导体纳米材料表面发生的电子转移过程; 5）将时间分辨红外线对金属亚硝基化合物和金属羰基化合物光化学的研究纳入本科课程。 位于布法罗的纽约州立大学的教师将分享使用这些设备的机会。这些研究将在生物化学、纳米科学和材料科学等许多领域产生影响。

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.
