Purchase of an EPR Spectrometer

在化学研究仪器和设施：系多用户仪器(CRIF：MU)计划的支持下，马萨诸塞大学阿默斯特分校化学系将获得一台电子顺磁共振(EPR)光谱仪。该仪器的主要用途将用于有机自由基、多自由基、硝烯、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、催化剂和活性中间体的溶解和冷冻基质研究。现代EPR仪器的可靠性和用户友好的软件将允许本科生研究人员常规使用该仪器，建议的仪器将成为招收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卖点。电子顺磁共振(EPR)光谱仪提供有关分子和电子结构的信息。它还可以用来获取有关自由基寿命的信息，自由基是一种寿命较短的物种，通常对启动肿瘤生长和/或各种化学反应至关重要。EPR研究可以在许多领域产生影响，从制造到材料和生物化学。

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.
