Acquisition of a Fourier Transform (X-band) Electron Paramagnetic Resonance Spectrometer

在化学研究仪器和设施(CRIF)计划的支持下，位于塔斯卡卢萨的阿拉巴马大学化学系将获得一台电子顺磁共振(EPR)光谱仪。将利用这一仪器的一些研究包括：a)介孔分子筛中类胡萝卜素光致电离的中间体的结构；b)多孔材料的形成；c)胰岛素信号色调蛋白寡肽内四核铬组件上的配体桥；以及d)蛋白质与光系统I的电子转移辅助因子的相互作用。电子顺磁共振(EPR)光谱仪是一种用于获得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。这些研究将在许多领域产生影响，特别是生物化学。

With support from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Alabama in Tuscaloosa will acquire an Electron Paramagnetic Resonance (EPR) Spectrometer. Some of the studies that will exploit this instrument include a) the structure of intermediates upon photoionization of carotenoids in mesoporous molecular sieves; b) formation of porous materials; c) ligand bridges on tetra-nuclear chromium assemblies within the insulin-signaling chromodulin oligopeptide; and d) interactions of the protein with electron transfer cofactors of Photosystem I. 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.
