Purchase of UV-Vis-Near-IR Raman Spectrometer

化学研究仪器项目的这一奖项将帮助犹他大学化学系获得一台拉曼光谱仪。拉曼光谱仪将用于以下研究项目：1)金属蛋白质的拉曼研究，2)介电固/液界面的化学结构和动力学，4)复杂Ni(III)和Ni(IV)氧化物的振动研究，5)有机金属体系中主客体相互作用的振动研究和6)固相链反应的拉曼光谱研究。拉曼光谱研究分子中的振动和转动跃迁。所获得的信息有时是对从红外研究中获得的信息的补充，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解决高背景荧光或样品光降解问题提供了强有力的解决方案，并提高了信噪比。拉曼光谱是研究凝聚相化学和生物分子体系的宝贵工具。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at the University of Utah acquire a Raman spectrometer. The Raman spectrometer will be used in research projects aimed at: 1) Raman studies of metalloproteins, 2) chemical structure and kinetics at dielectric solid/liquid interfaces, 4) vibrational studies of complex Ni(III) and Ni(IV) oxides, 5) vibrational studies of host-guest interactions in organometallic systems and 6) Raman spectroscopic studies of solid state chain reactions. 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, as well as enhanced signal-to-noise quality. Raman spectroscopy is an invaluable tool in studies of condensed-phase chemical and biomolecular systems.
