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.

化学研究仪器计划的奖项将帮助堪萨斯大学化学系获得傅立叶转换拉曼系统（FTR）。 FTR将用于针对1）对光活性蛋白Rhodopsin，bacteriohopopsin和Phtosythetic Reaction中心的能量转化机理的稳态和时间分辨研究的研究项目； 2）研究合成氧结合化合物中结构和氧结合的机制； 3）表征电极工艺和电子转移和细胞色素C3中的表征。 拉曼光谱与分子中的振动和旋转过渡有关。 获得的信息有时会得到从红外研究获得的补充，并提供有价值的结构信息。 带有近红外激发的傅立叶变换拉曼光谱学为高背景荧光或样品光降解或光降低以及增强的信号到噪声质量提供了有力的解决方案。 拉曼光谱学是凝结化学和生物分子系统研究的宝贵工具。
