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.

化学（12）反映了激光在科学研究，医疗实践和众多当前和新兴技术中的重要性，领先的化学课程已将激光实验纳入其先进的实验室课程。我们正在介绍激光实验在化学系课程的几个层次的一个项目，是中央对我们的目标，移动课程走向“研究模式”，学生与研究级仪器，设计实验，通过引导调查，并解释他们的主要研究文献的背景下的结果。我们正在实施的实验改编自化学教育杂志和小学化学研究文献，并从其他机构测试的程序修改。我们正在加强光谱实验室课程的创新目标：（1）让学生使用一套多功能的激光设备，以认识到源和检测器的能力和局限性如何影响实验设计，以及（2）设计两个基于研究的实验模块，使用适当的光谱工具解决生物无机光诱导电子转移和非线性光学。第二次调整将荧光寿命和激光光化学动力学测量纳入化学实验室介绍，并补充我们的外展工作与中学化学课程。这个项目支持了我们部门对师生合作研究的兴趣日益浓厚的趋势。随着新的化学设施，以支持仪器和新的教师在光谱学方面的专业知识，这是一个理想的时间引入激光光谱实验到我们的计划。
