Significant revisions are provided to the upper-level offerings in chemistry and biochemistry to make more explicit the connection between electronic structure and physical and chemical properties in a wide range of materials. This project purchases a .63 T electron paramagnetic resonance (EPR) spectrometer, an instrument of increasingly wide-use in both applied and basic research, ideally suited to illuminating the electronic structure of many important materials. In conjunction with the prior instrument holdings of the college, an EPR spectrometer enables the college to develop new laboratories incorporating recent advances in inorganic chemistry to help students better understand connections between chemical structure and function. An EPR spectrometer, in addition to existing equipment, also enables the college to develop an innovate immersion course in bioinorganic chemistry to be offered during the short-term. This intensive 5 days per week, 6 hours per day, 5-week course provides students with exposure to both the concepts and techniques of bioinorganic chemistry. This course serves both chemistry majors and the growing number of biochemistry majors. Projects developed for this course can serve as a model for undergraduate bioinorganic courses. Incorporation of an EPR-based project into the existing upper-level spectroscopy course provides an important additional dimension to the existing projects based on molecular beam spectroscopy and inductively coupled plasma atomic emission spectroscopy. Additionally, the EPR spectrometer markedly enhances the research opportunities available to students in the natural sciences. *

对化学和生物化学的上层课程进行了重大修订，以更明确地说明各种材料的电子结构与物理和化学性质之间的联系。 该项目购买了一台.63 T电子顺磁共振（EPR）光谱仪，这是一种在应用和基础研究中使用越来越广泛的仪器，非常适合阐明许多重要材料的电子结构。 结合学院先前的仪器持有，EPR光谱仪使学院能够开发新的实验室，结合无机化学的最新进展，帮助学生更好地了解化学结构和功能之间的联系。 EPR光谱仪，除了现有的设备，还使学院能够开发一个创新的浸入式课程在生物无机化学将在短期内提供。 这种密集的每周5天，每天6小时，为期5周的课程为学生提供接触生物无机化学的概念和技术。 本课程既为化学专业学生服务，也为越来越多的生物化学专业学生服务。 为这门课程所开发的专题可以作为本科生生物无机课程的范例。 将EPR为基础的项目纳入现有的高级光谱学课程，为基于分子束光谱学和电感耦合等离子体原子发射光谱学的现有项目提供了一个重要的额外维度。 此外，EPR光谱仪显着提高了学生在自然科学领域的研究机会。 *
