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.

化学研究仪器项目的​​这一奖项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) 光敏蛋白视紫红质、细菌视紫红质和光合反应中心能量转换机制的稳态和时间分辨研究； 2）合成氧结合化合物中氧结合的结构和机理研究； 3) 黄酶和细胞色素 c3 中电极过程和电子转移的表征。 拉曼光谱涉及分子的振动和旋转转变。 获得的信息有时会补充从红外研究中获得的信息并提供有价值的结构信息。 具有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稳定性问题以及增强的信噪比问题提供了强大的解决方案。 拉曼光谱是凝聚相化学和生物分子系统研究中的宝贵工具。
