Optical Instrumentation Upgrade and Purchase of a Laser Laboratory for Chemistry

该机构现代化了吸收和发光光谱领域的两个主要仪器，并创建了一个中央多功能激光实验室，用于高年级教学和学生研究。仪器和两个激光光源的输出都将连接到同一个中央微型计算机上。这些光谱技术的能力已经扩展到允许计算机数据采集和分析，用于物理化学，仪器分析，聚合物，专题和独立/定向研究的实验课程，以及部门本科研究项目。激光实验室让学生认识和使用激光光源的独特能力。这些设备包括氦氖激光器、氦镉激光器和氮泵染料激光器，此外还有相关的光学设备、单色仪、探测系统和用于实验控制和数据分析的微型计算机。在教学实验室中，用连续宽带光源和单色激光光源进行了新颖的吸收和发光测量。这些都集中在物理和化学性质的方式，更清楚地阐明了材料的光学效应，并说明了现代光学技术的力量。独立学习和研究项目涉及固体激光染料材料的光谱照明实验，作为表面活性剂和胶束系统的光谱探针，以及与EDTA结合的镧系生物有机配体的pH依赖聚合行为。该机构为该项目提供的资金相当于国家科学基金会的资金。

The institution modernized two major instruments in the areas of absorption and luminescence spectroscopy and created a central multi-functional laser laboratory for use in upper division teaching and student research. Both instruments and the output from two laser light sources will be interfaced to the same central microcomputer. Capabilities in each of these spectroscopic techniques have been expanded to allow for computerized data acquisition and analysis for use in laboratory courses in physical chemistry, instrumental analysis, polymers, special topics and independent/directed study as well as in departmental undergraduate research projects. The laser laboratory allows students to realize and work with the unique capabilities of laser light sources. These include a He-Ne laser, a He-Cd laser and a nitrogen-pumped dye laser in addition to associated optics, a monochrometer, a detection system and a microcomputer for experiment control and data analysis. In the teaching labs novel absorption and luminescence measurements are made from continuous broad band sources and monochromated laser sources. These are focused on physical and chemical properties in ways which more clearly elucidate optical effects in materials as well as illustrate the power of modern optical techniques. Independent study and research projects involve experiment dealing with the spectroscopic illumination of laser dye materials in the solid state, as spectroscopic probes in surfactant and micelle based systems, and in the pH dependent polymeric behavior of bioorganic ligand bonded to lanthanides in association with EDTA. The institution contributed to this project in an amount equal to the NSF funds.
