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

在重大研究仪器(MRI)计划的支持下，位于布法罗的纽约州立大学化学系将获得一台用于研究化学和生物分子系统中光诱导物种的步进扫描时间分辨FTIR和脉冲Nd-YAG泵浦激光器。拟议的仪器将用于：1)补充正在进行的时间分辨X射线结晶学研究，旨在阐明伴随着短寿命光激发态的形成的几何变化；2)阐明氢酶激活和分解氢的过程中活性部位和周围蛋白质发生的变化；3)研究天然形式的钙调蛋白与嵌入在干凝胶中的钙调蛋白激活的本质差异；4)表征半导体纳米材料表面发生的电子转移过程；5)将关于金属亚硝基和金属羰基的光化学的时间分辨红外研究纳入本科生课程。纽约州立大学布法罗分校的教职员工将共享这一设备。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。

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.
