项目摘要

Laser-based instruments for optical spectroscopy provide new and exciting experiences for students in undergraduate physical chemistry and analytical chemistry courses. This project incorporates miniature pulsed Nd:YAG and tunable dye lasers into several experiments designed to illustrate key features of molecular structure and dynamics. Students are using lasers to record spectra with much higher resolution than is offered by traditional spectroscopic instruments. Fine structure observed in laser-based spectra reveal couplings between molecular motions that students often struggle to visualize. Time-resolved laser-induced-fluorescence studies illustrate the competition between radiative and nonradiative relaxation mechanisms. Multiphoton excitation and resonance-ionization spectroscopy using short pulses can introduce fast electro-optic technology into physical and analytical chemistry courses. Laser Raman spectroscopy complements existing nuclear magnetic resonance, gas chromatograph/mass spectroscopy, and Fourier-transform infrared capabilities for chemical identification in synthesis courses. Students engaged in undergraduate research gain hands-on experience with individual hardware components in modular instrument configurations. The presence of modern spectroscopy in the undergraduate curriculum strongly enhances student preparation for advanced-degree programs in chemistry, medicine, and engineering.
基于激光的光学光谱仪器为本科物理化学和分析化学课程的学生提供了新的和令人兴奋的体验。该项目将微型脉冲激光和可调谐染料激光器结合到几个实验中,以阐明分子结构和动力学的关键特征。学生们正在使用激光记录光谱,其分辨率远远高于传统光谱仪器提供的分辨率。在激光光谱中观察到的精细结构揭示了分子运动之间的耦合,这是学生们经常难以想象的。时间分辨激光诱导荧光研究阐明了辐射和非辐射弛豫机制之间的竞争。使用短脉冲的多光子激发和共振电离光谱可以将快速电光技术引入物理化学和分析化学课程。激光拉曼光谱补充了现有的核磁共振、气相色谱/质谱仪和傅立叶变换红外光谱在合成过程中进行化学识别的能力。从事本科生研究的学生将获得使用模块化仪器配置中的单个硬件组件的实践经验。现代光谱学在本科课程中的出现极大地加强了学生为化学、医学和工程学高级学位课程的准备。
