Introduction of Modern Laser Techniques into the Undergraduate Chemistry Curriculum

Clifford J. Creswell DUE 9551252 Hamline University FY1995 $18,593 Saint Paul， MN 55104 ILI -仪器仪表项目：化学现代激光技术引入本科化学课程设备的购买将使我们能够在化学课程中引入激光技术。哈姆林大学将获得激光器、光探测组件、单色仪、信号处理设备和数据采集设备。本文介绍了单光子吸收和双光子吸收激光诱导荧光光谱的实验研究。将介绍涉及Ru（II）配位配合物激发态的实验，以演示处理和评估纳米到毫秒时间范围内的动力学事件的方法。所有实验都具有开放性，使学生能够探索激光光谱学的其他方面。我们普通化学课程的学生也将通过高年级同学的演示/研讨会来接触这项技术。这些研讨会将使我们对化学中一些激动人心的概念有一个安全有趣的预习。所要求的设备还将用于本科研究项目，例如比较Os（II）配合物与类似Ru（II）配合物的电子转移能力。

Hamline University will acquire lasers, light detecting components, a monochromator, signal processing equipment, and data acquisition equipment. Laboratory experiments will be introduced for the study of laser-induced fluorescence spectroscopy using single photon absorption and two photon absorption. Experiments involving excited states of Ru(II) coordination complexes will be introduced to demonstrate methods for handling and evaluating kinetic events in the nano to millisecond time range. All experiments have an open-ended quality to them which allows students to explore other aspects of laser spectroscopy. Students in our general chemistry course will also be exposed to this technology through demonstrations/seminars presented by their upper-division peers. These seminars will enable a safe interesting preview of some exciting concepts in chemistry. The requested equipment will also be used in undergraduate research projects such as in a comparison of the electron transfer ability of Os(II) complexes to that of the analogous Ru(II) complexes.
