With support from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation (CRIF:MU) Program, the Department of Chemistry at the University of Massachusetts Amherst will acquire an Electron Paramagnetic Resonance (EPR) Spectrometer. The main usage of this instrument will be for solution and frozen matrix investigation of organic radicals, polyradicals, nitrenes, carbenes, coordination complexes of paramagnetic ions (both biological and non-biological), magnetic materials, polymers, catalysts, and reactive intermediates. The dependability and user-friendly software of a modern EPR instrument will allow undergraduate researchers to use the instrument routinely and the proposed instrument will be a selling point for recruiting minority and underrepresented students to participate in the Northeast Alliance for Graduate Education and Professoriate. The student training on the EPR instrument will also make graduates more competitive in the industrial sector.An electron paramagnetic resonance (EPR) spectrometer yields information on the molecular and electronic structure of molecules. It may also be used to obtain information about the lifetimes of free radicals, short-lived species that are often essential for the initiation of tumor growth and/or a variety of chemical reactions. EPR studies can have an impact in a number of areas, from manufacturing to materials and biological chemistry.

在化学研究仪器和设施：部门多用户仪器 (CRIF:MU) 计划的支持下，马萨诸塞大学阿默斯特分校化学系将购买一台电子顺磁共振 (EPR) 光谱仪。该仪器的主要用途是对有机自由基、多自由基、氮宾、卡宾、顺磁性离子（生物和非生物）的配位络合物、磁性材料、聚合物、催化剂和反应中间体进行溶液和冷冻基质研究。现代 EPR 仪器的可靠性和用户友好型软件将使本科研究人员能够常规使用该仪器，并且拟议的仪器将成为招募少数族裔和代表性不足的学生参加东北研究生教育和教授联盟的一个卖点。 EPR 仪器的学生培训也将使毕业生在工业领域更具竞争力。电子顺磁共振 (EPR) 波谱仪可提供有关分子和电子结构的信息。它还可用于获取有关自由​​基、短命物质的寿命的信息，这些物质通常对于肿瘤生长和/或各种化学反应的启动至关重要。 EPR 研究可以对从制造到材料和生物化学的许多领域产生影响。
