This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Similar to subproject 0096, a practical course showing basic principles of ESR spectroscopy was offered by ACERT, this time for students of inorganic chemistry (CHEM606). Unlike subproject 0096, this course is focused on demonstration of a vast range of ESR spectra and applications of ESR spectroscopy rather than offering a single problem to be solved with ESR. In the new course students learn about the g-factor and hyperfine splitting effects, their anisotropy, ESR in gaseous phase, isotopes, motion effects, spin exchange etc. We use a number of inorganic and organic compounds giving a variety of ESR spectra: nitroxide radicals, salts and complex compounds of copper, manganese, chromium, vanadium and nickel, molecular oxygen at reduced pressure. Students record and explain spectra of single crystals, powders, liquid and frozen solutions, gaseous samples.

该子项目是利用资源的众多研究子项目之一 由 NIH/NCRR 资助的中心拨款提供。子项目的主要支持 并且子项目的首席研究员可能是由其他来源提供的， 包括其他 NIH 来源。 子项目可能列出的总成本 代表子项目使用的中心基础设施的估计数量， NCRR 赠款不直接向子项目或子项目工作人员提供资金。 与子项目 0096 类似，ACERT 为无机化学学生（CHEM606）开设了一门展示 ESR 光谱基本原理的实践课程。与子项目 0096 不同，本课程侧重于演示各种 ESR 光谱和 ESR 光谱的应用，而不是提供 ESR 需要解决的单一问题。 在新课程中，学生将了解 g 因子和超精细分裂效应、它们的各向异性、气相 ESR、同位素、运动效应、自旋交换等。我们使用多种无机和有机化合物来提供各种 ESR 光谱：硝基氧铜、锰、铬、钒和镍的自由基、盐和复杂化合物、减压下的分子氧。学生记录并解释单晶、粉末、液体和冷冻溶液、气体样品的光谱。
