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

这项来自化学研究仪器计划和国家设施和仪器计划的奖项将帮助俄勒冈州立大学化学系获得一种可调谐的染料激光系统。该激光器将用于1)新固体光学研究和2)非线性拉曼光谱研究项目。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本底荧光或样品的光降解或光解性以及提高信噪比质量提供了强有力的解决方案。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 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.
