Laser Spectroscopy Equipment for an Undergraduate Chemistry Laboratory

在这个项目中，我们组装了多功能激光光谱仪的基本部件，使我们的化学专业能够进行拉曼光谱、时间分辨吸收光谱和时间分辨荧光光谱的实验。整个系统包括脉冲氮激光器和染料激光器，以及用于存储和分析数据的单色仪、信号处理器和实验室计算机。分光计用来向学生介绍几种对当前化学研究很重要的现象和技术。这些课程包括(A)激光的原理和应用，(B)测量非常快的过程的技术，以及(C)计算机接口和实验控制。这也为我们的化学专业的学生提供了一个机会，可以使用最先进的激光设备进行独立的研究项目。该机构正在将NSF的拨款与同等数额的资金相匹配。

In this project the essential components of versatile laser spectrometer is assembled that enables our chemistry major to carry out experiments in Raman spectroscopy, time-resolved absorption spectroscopy, and time-resolved fluorescence spectroscopy. The total system includes both a pulsed nitrogen laser and a dye laser, as well as a monochromator, a signal processor, and a laboratory computer to store and analyze the data. The spectrometer is used to introduce students to several phenomena and techniques which are important to current research in chemistry. These include (a) principles and applications of lasers, (b) techniques for measuring very fast processes, and (c) computer interfacing and control of experiments. This also provides an opportunity for our chemistry majors to use state-of-the-art laser equipment for independent research projects. The institution is matching the NSF grant with an equal amount of funds.
