An Expansion of the Purdue Chemistry Departmental Laser Facility: A Versatile Raman/Fluorescence Instrument and Wavelength Extension in the Ultraviolet

9313345兹维尔这项来自化学研究仪器和设施计划的奖项将帮助普渡大学化学系购买拉曼/荧光仪器。这一新的仪器将加强以下领域的研究：摩擦学条件下自由基反应动力学的泵浦-探测研究，无机电子转移反应中间产物的时间分辨拉曼光谱，卟啉-DNA激基复合体的瞬时拉曼研究，以及分子掺杂和功能化聚合物薄膜电晕极化过程中和之后作为取向有序探针的波导拉曼光谱。该光谱仪还将用于收集超音速喷射中分子团簇的分散荧光光谱，以及用于催化应用的沸石锚定双金属络合物的拉曼研究。拉曼激光光谱仪可以提供有关溶液和表面的分子结构、分子相互作用和分子动力学的重要信息。这类信息对于基本理解化学反应是必要的。

9313345 Zwier This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at Purdue University in the purchase of a Raman/fluorescence instrument. This new instrumentation will enhance the research in a number of areas including the following: Pump-probe studies of radical reaction dynamics under tribological conditions, time-resolved Raman spectroscopy of intermediates in inorganic electron transfer reactions, transient Raman studies of porphyrin-DNA exciplexes, and waveguide Raman spectroscopy as a probe of orientational order during and after corona poling of molecularly doped and functionalized polymer films. The spectrometer will also be used to collect dispersed fluorescence spectra of molecular clusters in a supersonic jet and for Raman studies of zeolite anchored bimetallic complexes for catalytic applications. %%% A Raman laser spectrometer can provide important information about molecular structure, molecular interactions and molecular dynamics in solution and on surfaces. This sort of information is necessary for a basic understanding of chemical reactions.
