This project supports the use of a versatile, laser-based spectroscopy system in the undergraduate physical chemistry laboratory. The use of lasers in graduate, postdoctoral, and professional research makes it imperative that students be proficient in this area. The department has recently obtained a small Helium-Neon (HeNe) laser in order to carry out introductory laser experiments in the undergraduate laboratory. However, to ensure that this is not the only level of instruction that any of the students receive with lasers, this project outfits the undergraduate physical chemistry laboratory with the necessary equipment to teach more advanced laser-based experimentation. The acquisition of the Nitrogen-laser-pumped dye laser (N2-dye) system allows for the introduction of an integrated laser-based curriculum into this undergraduate laboratory course and of related techniques for the Instrumental Analysis and Biochemistry laboratories. The laser-based experiments complement and enhance experiments already performed in these courses. The laser system is being used for Raman and fluorescence spectroscopy and has the potential to be used for time-resolved experiments in the future. An original experiment utilizing surface-enhanced Raman spectroscopy (SERS) is currently being developed and introduced into the laboratory curriculum. The impact of the new experiments can be evaluated by comparing student course questionnaires with those of past semesters when no laser-based experiments were used and when many students explicitly requested more up-to-date equipment. Original experiments for the undergraduate physical chemistry laboratory can be submitted to the Journal of Chemical Education and discussed at meetings of the American Chemical Society(ACS). The SERS experiment currently under development may be presented at the ACS Biennial Conference of Chemical Education in Clemson, South Carolina, in August 1996. A lab manual is being compiled with the new experiments and may be made available over the Internet as well as in printed form.

该项目支持在本科生物理化学实验室中使用基于激光的多功能光谱系统。激光在研究生、博士后和专业研究中的使用使得学生必须精通这一领域。该系最近获得了一台小型氦氖（HeNe）激光器，以便在本科生实验室进行入门激光实验。然而，为了确保这不是任何学生接受激光的唯一指导水平，该项目为本科生物理化学实验室配备了必要的设备来教授更先进的基于激光的实验。 收购氮激光泵浦染料激光（N2-染料）系统可以将基于激光的集成课程引入本本科实验室课程以及仪器分析和生物化学实验室的相关技术。基于激光的实验补充和增强了这些课程中已经进行的实验。该激光系统用于拉曼光谱和荧光光谱，并有可能在未来用于时间分辨实验。目前正在开发一项利用表面增强拉曼光谱 (SERS) 的原创实验，并将其引入实验室课程。 新实验的影响可以通过将学生课程问卷与过去学期的问卷进行比较来评估，当时没有使用基于激光的实验，并且许多学生明确要求更先进的设备。本科生物理化学实验室的原创实验可以提交给《化学教育杂志》并在美国化学会（ACS）会议上进行讨论。目前正在开发的 SERS 实验可能会在 1996 年 8 月在南卡罗来纳州克莱姆森举行的 ACS 化学教育双年度会议上进行展示。正在编写新实验的实验室手册，并且可以通过互联网以及印刷版提供。形式。
