MRI: Acquisition of Instrumentation for the Manipulation and Laser Spectroscopic Characterization of New Complexes

在主要研究仪器（MRI）项目的支持下，西肯塔基大学化学系将获得一个色散拉曼光谱仪和一个现有氮泵浦染料激光器的检测系统。该设备将加强许多领域的研究，包括a)环烷与芳香族分子形成主客体配合物的光谱研究；b)四氧化锇n -杂环碳配合物的合成与振动光谱分析；c)发光光谱研究镧系离子与螯合和大环配体的配合物。拉曼光谱提供了一个强大的分子信息探针。拉曼散射与红外吸收是互补的，因为它探测的是根本不同类型的分子振动模式。对于生物样品，拉曼散射是首选的方法，因为它不受极性水环境的影响，在红外强吸收。这些研究将对生物科学和环境科学以及制药业产生影响。

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.
