Purchase of an EPR Spectrometer

在化学研究仪器和设施(CRIF)计划的这一奖项下，加州大学河滨分校的化学系将获得一台电子顺磁共振(EPR)光谱仪。EPR光谱学将在以下研究项目中发挥重要作用：a)生物无机化学或铁卟啉，富勒烯的氧化还原化学，金属卟啉/富勒烯超分子化学和元素周期表上的反应性自由基阳离子(Reed)；b)多卟啉阵列中的卟啉阳离子的表征(Bocian)；c)碳纳米管和中性有机导体的研究(Haddon)；d)光系统II中锰催化水氧化的机理研究(DEBUS)；e)捕获氟羰基(Morton)；以及f)开发用于评估手性的新型分析工具(Mueller)。电子顺磁共振(EPR)光谱仪是一种用于获取分子的分子和电子结构信息的仪器。它还可以用来获得有关自由基寿命的信息，这些自由基通常是启动肿瘤生长和/或各种化学反应所必需的。这些研究将在一些领域产生影响，特别是生物化学和材料科学。

With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of California in Riverside will acquire an Electron Paramagnetic Resonance (EPR) Spectrometer. Among the research programs in which EPR spectroscopy will play a vital role are: a) bioinorganic chemistry or iron porphyrins, redox chemistry of fullerenes, metalloporphyrin/fullerene supramolecular chemistry and reactive radical cations across the periodic table (Reed); b) characterization of porphyrin pi-cation radicals in multiporphyrin arrays (Bocian); c) studies on carbon nanotubes and neutral organic conductors (Haddon); d) investigations on the mechanism of manganese catalyzed water oxidation in photosystem II (Debus); e) trapping of fluorocarbonyl radicals (Morton); and f) development of new analytical tools for assessing chirality (Mueller). An electron paramagnetic resonance (EPR) spectrometer is an instrument used to obtain information about the molecular and electronic structure of molecules. It may also be used to obtain information about the lifetimes of free radicals which are often essential for the initiation of tumor growth and/or a variety of chemical reactions. These studies will have an impact in a number of areas, in particular biological chemistry and materials sciences.
