MRI: Acquisition and Construction of a Combined X-Band/Q-Band CW EPR/ENDOR Spectrometer

在主要研究仪器（MRI）计划的支持下，新墨西哥州大学的Martin Kirk和同事将获得一个组合的X波段/Q波段CW EPR/ENDOR光谱仪。 将利用这一仪器的项目包括：a）对生物酶和相关模型复合物的研究; B）对热诱导电荷转移材料的研究; c）将钴用作金属蛋白中锌位点的光谱探针; d）对高对称性钴配位化合物的光谱研究;以及e）对光合作用水氧化和铁调节的生物物理研究。电子顺磁共振（EPR）光谱仪是一种用于获得分子和分子电子结构信息的仪器。它还可以用来获得有关自由基的寿命的信息，这些自由基通常是肿瘤生长和/或各种化学反应的起始所必需的。 这些研究将在一些领域产生影响，特别是生物化学。

With support from the Major Research Instrumentation (MRI) Program, Martin Kirk and colleagues at the University of New Mexico will acquire a combined X-band/Q-band CW EPR/ENDOR spectrometer. Projects that will exploit this instrument include a) studies of molybdoenzymes and relevant model complexes; b) research on thermally induced charge transfer materials; c) the use of cobalt as a spectroscopic probe of zinc sites in metalloproteins; d) spectroscopic studies of high symmetry cobalt coordination compounds; and e) biophysical studies of photosynthetic water oxidation and iron regulation. 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.
