Purchase of a Fourier Transform Raman Spectrometer

化学研究仪器项目的这一奖项将帮助佛罗里达州立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.合成聚合物的表征，特别是对理解相结构及其与其他结构因素和性质的关系至关重要的模型体系。2.复杂样品中有机物种分析技术的发展，重点是化学计量学技术在液体和固体拉曼光谱中的应用。3.导电有机聚合物导电机理和性质的测定。4.腐植酸和黄腐酸中官能团的金属结合效应的表征。5.热改性和化学改性硅胶的表面化学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 Florida State University acquire a Fourier-transform Raman system (FTR). The FTR will be used in research projects aimed at: 1. Characterization of synthetic polymers, particularly model systems essential to understanding phase structure and its relation to other structural factors and properties. 2. Development of analytical techniques for organic species in complex samples, emphasizing chemometric techniques applied to Raman spectrocopy of liquids and solids. 3. Determination of conduction mechanisms and properties of conducting organic polymers. 4. Characterization of metal binding effects on functional groups in humic and fulvic acids. 5. Study of surface chemistry of thermally and chemically modified silica gels. 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.
