This project supports the department's use of a Nd:YAG-pumped dye laser and the associated electronics equipment in the undergraduate chemistry program. Incorporation of a pulsed, tunable laser into the teaching and research laboratories reflects contemporary research activities in physical and inorganic chemistry. The new instrumentation has a major impact on the upper-division teaching and laboratory courses. Beginning with the spectroscopy laboratory of the physical chemistry sequence, students learn the basics of lasing and tuning, collecting signals, data acquisition, and instrument-to-computer interfacing. They then apply this know-how to collecting the absorption spectra of Neon and Argon. Building on this experiment, students measure and assign the one- and two-photon absorption spectra of phenanthrene. In the senior-level inorganic laboratory, students use the equipment to investigate the long-range electron-transfer kinetics through metalloproteins. Here, they learn the fundamentals of transient absorption and emission spectroscopy. Additionally, the laser system may be used extensively in two undergraduate research laboratories, one that focuses on inorganic photochemistry and the other, on materials research.

该项目支持该部门在本科化学课程中使用Nd：YAG泵浦染料激光器和相关的电子设备。将脉冲可调谐激光器纳入教学和研究实验室反映了物理和无机化学的当代研究活动。新仪器对高年级的教学和实验室课程产生了重大影响。从物理化学序列的光谱实验室开始，学生学习激光发射和调谐，收集信号，数据采集和仪器到计算机接口的基础知识。然后，他们将这一技术应用于收集氖和氩的吸收光谱。在这个实验的基础上，学生测量并分配菲的单光子和双光子吸收光谱。在高级无机实验室，学生使用设备来研究通过金属蛋白的远程电子转移动力学。在这里，他们学习瞬态吸收和发射光谱的基本原理。此外，激光系统可广泛用于两个本科研究实验室，一个侧重于无机光化学，另一个侧重于材料研究。
