With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Western Kentucky University will acquire a dispersive Raman spectrometer and a detection system for an existing nitrogen-pumped dye laser. This equipment will enhance research in a number of areas including a) spectroscopic investigation of the formation of host-guest complexes of cyclophanes with aromatic molecules; b) synthesis and vibrational spectroscopy of N-heterocyclic carbene complexes of osmium tetroxide; and c) luminescence spectroscopy to investigate the complexes of lanthanide ions with chelating and macrocyclic ligands. Raman spectroscopy provides a powerful probe of molecular information. Raman scattering is complementary to infrared absorption in that it probes fundamentally different types of molecular vibrational modes. For biological samples, Raman scattering is the preferred method because it is not affected by the polar water environment that absorbs strongly in the infrared. These studies will have an impact in the biological and environmental sciences, and the pharmaceutical industry.

在主要研究仪器（MRI）计划的支持下，西肯塔基州大学化学系将获得一台色散拉曼光谱仪和一台现有氮泵浦染料激光器的检测系统。这一设备将加强若干领域的研究，包括a）环番与芳香分子形成主客体络合物的光谱研究; B）四氧化锇N-杂环卡宾络合物的合成和振动光谱; c）研究镧系元素离子与螯合配体和大环配体络合物的发光光谱。拉曼光谱学提供了一种强有力的分子信息探针。 拉曼散射与红外吸收互补，因为它探测根本不同类型的分子振动模式。 对于生物样品，拉曼散射是优选的方法，因为它不受在红外中强烈吸收的极性水环境的影响。 这些研究将对生物和环境科学以及制药业产生影响。
