Tunable Pulsed Laser System for Nonlinear Raman Spectroscopyand Optical Studies of Solids

这份来自化学研究仪器计划和国家设施和仪器计划的合同将帮助俄勒冈州立大学化学系获得Nd:YAG可调谐染料激光系统。该激光器将用于新固体的光学研究和非线性拉曼光谱的研究项目。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 and the National Facilities and Instrumentation Program will help the Department of Chemistry at Oregon State University acquire a Nd:YAG tunable dye laser system. The laser will be used in research projects aimed at 1) Optical Studies of New Solids and 2) Nonlinear Raman Spectroscopy. 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.
