Linda Peteanu of Carnegie-Mellon University is supported by the Theoretical and Computational Chemistry Program to investigate excited-state intramolecular proton transfer reactions in the condensed phase. She will use Stark spectroscopy to obtain experimental data regarding the charge distributions and structures of molecules that undergo excited-state intramolecular proton transfer. The dipole moments and polarizabilities that will be measured are critically needed to model the effects of the solvent media on the rates of proton transfer reactions. Ideas for extending an understanding of spectroscopic techniques into the classroom and teaching laboratory will be implemented. These include (a) the design of a course in molecular spectroscopy that incorporates research literature as a teaching tool; (b) the integration of research-based techniques into the physical chemistry laboratory; (c) the incorporation of research-based skills in electronics and optics into the laboratory to increase students' understanding of scientific equipment; and (d) introduction of lasers. Problem-solving skills will be emphasized.

卡内基梅隆大学的 Linda Peteanu 在理论和计算化学项目的支持下研究凝聚相中的激发态分子内质子转移反应。 她将使用斯塔克光谱来获得有关经历激发态分子内质子转移的分子的电荷分布和结构的实验数据。 模拟溶剂介质对质子转移反应速率的影响时，需要测量偶极矩和极化率。 将光谱技术的理解扩展到课堂和教学实验室的想法将得到实施。 其中包括 (a) 设计分子光谱学课程，将研究文献作为教学工具； (b) 将研究技术纳入物理化学实验室； (c) 将电子和光学方面的研究技能纳入实验室，以增加学生对科学设备的了解； (d) 引入激光器。 将强调解决问题的能力。
