Upgrade of a Cyber-Enabled Electron Paramagnetic Resonance (EPR) Spectrometer for Research and Education

在化学研究仪器和设施-多用户仪器(CRIF-MU)计划的支持下，威斯康星大学化学系将升级一台联网的电子顺磁共振(EPR)光谱仪。受益于EPR光谱仪的研究项目包括：1)高价金属中心与氧化还原活性单元之间的相互作用；2)腺苷钴胺的生物合成和反应；3)气敏金属蛋白；4)用于量子信息处理的硅自旋共振；5)星际空间中的有机分子；以及6)硅、锗和锡的低配位和多键化合物。电子顺磁共振(EPR)光谱仪提供有关分子和分子电子结构的信息。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光谱仪将进行网络基础设施升级，以允许几个学术机构进行远程控制，这些机构拥有大量代表不足的少数民族人口。

With support from the Chemistry Research Instrumentation and Facilities - Multiuser Instrumentation (CRIF-MU) Program, the Department of Chemistry at the University of Wisconsin will upgrade a cyber-enabled electron paramagnetic resonance (EPR) spectrometer. Research projects to benefit from the EPR spectrometer include studies on 1) the interaction between high-valent metal centers and redox active units; 2) the biosynthesis and reactivity of adenosyl-cobalamin; 3) gas sensing metalloproteins; 4) silicon spin resonance for quantum information processing; 5) organic molecules that occur in interstellar space; and 6) low-coordinate and multiply-bonded compounds of silicon, germanium, and tin. 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. The EPR spectrometer will undergo a cyber-infrastructure upgrade to allow remote control by several academic institutions with significant populations of underrepresented minorities.
