Purchase of a Fourier-Transform Raman/Infrared Step-Scan Spectrometer

这份来自化学研究仪器项目的合同将帮助堪萨斯大学化学系获得傅里叶变换拉曼系统（FTR）。FTR将用于以下研究项目：1)光活性蛋白视紫红质、细菌视紫红质和光合反应中心的能量转换机制的稳态和时间分辨研究；2)合成的氧结合化合物的结构及氧结合机理的研究；3)黄酮类酶和细胞色素c3的电极过程和电子转移表征。拉曼光谱研究分子中的振动和旋转跃迁。获得的信息有时与红外研究获得的信息相补充，并提供有价值的结构信息。近红外激发的傅里叶变换拉曼光谱为高背景荧光或样品光降解或光致性问题提供了强有力的解决方案，并增强了信噪比质量。拉曼光谱是研究凝聚态化学和生物分子系统的宝贵工具。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at the University of Kansas acquire a Fourier-transform Raman system (FTR). The FTR will be used in research projects aimed at 1) steady-state and time-resolved studies of the mechanism of energy conversion in the photoactive proteins rhodopsin, bacteriohodopsin, and photosynthetic reaction centers; 2) investigations of structure and the mechanism of oxygen binding in synthetic oxygen-binding compounds; and 3) characterization of electrode processes and electron transfer in flavoenyzmes and cytochrome c3. Raman Spectroscopy is concerned with vibrational and rotational transitions in molecules. The information obtained sometimes complements that obtained from an infrared study and provides valuable structural information. Fourier-transform Raman spectroscopy with near-infrared excitation provides a powerful solution to problems of high background fluorescene or sample photodegradation or photolability and enhanced signal-to-noise quality. Raman spectroscopy is an invaluable tool in studies of condensed-phase chemical and biomolecular systems.
