Laser Spectroscopy to Enhance Inquiry-Mode Laboratories in Chemistry

反映了激光在科学研究、医疗实践以及众多当前和新兴技术中的重要性，领先的化学专业将激光实验纳入了他们的高级实验课程。我们在化学系课程的几个层次引入激光实验，这个项目是我们将课程推向“研究模式”的核心目标，在这种模式下，学生使用研究级仪器，通过引导探究设计实验，并在主要研究文献的背景下解释他们的结果。我们正在实施的实验改编自《化学教育杂志》和初级化学研究文献，并根据其他机构测试的程序进行了修改。我们正在加强光谱学实验课程，其创新目标是：(1)让学生使用一套多功能激光设备来认识光源和探测器的能力和局限性如何影响实验设计；(2)设计两个基于研究的实验模块，使用适当的光谱学工具来解决生物无机光致电子转移和非线性光学问题。第二次调整将荧光寿命和激光光化学动力学测量纳入入门化学实验室，并补充我们与中学化学课程的推广工作。这个项目支持了我们系对师生合作研究越来越感兴趣的趋势。有了新的化学设施来支持仪器和具有光谱学专业知识的新教员，这是将激光光谱学实验引入我们项目的理想时机。

Chemistry (12)Reflecting the importance of lasers in scientific research, medical practice, and numerous current and emerging technologies, leading chemistry programs have incorporated laser experiments into their advanced laboratory courses. We are introducing laser experiments at several levels of the Chemistry Department curriculum in a project that is central to our goal of moving the curriculum toward a "research model" in which students work with research-grade instrumentation, design experiments through guided inquiry, and interpret their results within the context of primary research literature. The experiments we are implementing are adapted from the Journal of Chemical Education and from primary chemistry research literature and are modified from procedures tested at other institutions. We are enhancing a Spectroscopy Laboratory course with the innovative goals of: (1) having students work with a versatile set of laser equipment to recognize how the capabilities and limitations of sources and detectors affect experimental design, and (2) designing two research-based experimental modules which address bio-inorganic photoinduced electron transfer and nonlinear optics using the appropriate spectroscopy tools. A second adaptation incorporates fluorescence lifetime and laser photochemical kinetic measurements into an Introductory Chemistry Laboratory and supplements our outreach efforts with secondary school chemistry programs. This project supports a trend in our department of increasing interest in student-faculty collaborative research. With new chemistry facilities to support instrumentation and new faculty members with expertise in spectroscopy, this is an ideal time to introduce laser spectroscopy experiments into our program.
