MRI: Aquisition of an EPR Spectrometer

该奖项由化学部门和主要研究仪器（MRI）项目共同资助，来自芝加哥洛约拉大学的Richard Holz教授将获得一台配备低温液氦能力的电子顺磁共振光谱仪和一个垂直和平行模式的X波段腔。该提案旨在加强各级的研究培训和教育，特别是在诸如金属水解酶和金属水解酶的研究、金属中心的生物学相关、双核金属结合位点在ADP葡萄糖焦磷酸化酶中的催化作用、氨基肽酶P双核活性位点的电子和催化性质等研究领域。鸟嘌呤核苷酸结合蛋白α亚基的Mn（II）和二价VO金属取代衍生物与铜、锌超氧化物歧化酶及低温下X波段EPR的应用EPR光谱仪产生分子和固态材料的几何和电子结构的详细信息。它还可用于获取自由基的寿命信息，这些自由基是参与有价值的化学转化以及病理性肿瘤生长起始的短命、高活性物质。这些研究将影响许多领域，从无机和有机分子的合成到新的固态材料的开发，再到生物兴趣化合物。从正在进行的研究中汲取灵感，该仪器将成为本科生和研究生研究和教学的一个组成部分。

With this award, co-funded by the Division of Chemistry and the Major Research Instrumentation (MRI) program, Professor Richard Holz from Loyola University of Chicago will acquire an electron paramagnetic resonance spectrometer equipped with low temperature liquid helium capabilities and an X band cavity operational in both perpendicular and parallel modes. The proposal is aimed at enhancing research training and education at all levels, especially in areas of study such as investigations of metallohydrolases and metallohydratases, biologically relevant metal centers, catalytic role of the dinuclear metal binding site in ADP glucose pyrophosphorylase, electronic and catalytic properties of the dinuclear active site of Aminopeptidase P, Mn(II) and divalent VO metal substituted derivatives of alpha subunits of guanine nucleotide binding proteins and copper, zinc superoxide dismutase and applications of X band EPR at low temperatures.An EPR spectrometer yields detailed information on the geometric and electronic structure of molecular and solid state materials. It may also be used to obtain information about the lifetimes of free radicals, short-lived, highly reactive species involved in valuable chemical transformations as well as the initiation of pathological tumor growth. These studies will impact a number of areas, from the synthesis of inorganic and organic molecules to the development of new solid state materials to compounds of biological interest. Employing examples inspired from ongoing research, this instrument will be an integral part of research and teaching at the undergraduate and graduate levels.
