With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Alabama in Tuscaloosa will acquire a High Field (W-Band) Electron Paramagnetic Resonance (EPR) Spectrometer. Among the research programs in which EPR spectroscopy will play a vital role are: a) the study of carotenoids as radical scavengers; b) the mechanism of formation of mesoporous silicas; c) use of molecular genetics and high-field EPR to identify and characterize the binding site of the phylloquinone cofactor in Photosystem I; d) ferromagnetic resonance studies of high-anisotropy magnetic media; e) studies of biologically-relevant first row transition metal assemblies; and f) EPR spectroscopy of localized radical cations within redox-gradient dendrimers.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, especially materials science and biochemistry.

通过这项来自主要研究仪器（MRI）项目的奖励，位于塔斯卡卢萨的阿拉巴马大学化学系将获得一台高场（w波段）电子顺磁共振（EPR）光谱仪。EPR光谱将发挥重要作用的研究项目包括：a)类胡萝卜素作为自由基清除剂的研究；B)介孔二氧化硅的形成机理；c)利用分子遗传学和高场EPR鉴定和表征光系统I中叶绿醌辅因子的结合位点；D)高各向异性磁介质的铁磁共振研究；E)与生物学相关的第一排过渡金属组件的研究；和f)氧化还原梯度树状大分子中局部自由基阳离子的EPR光谱。电子顺磁共振（EPR）谱仪是一种用于获取分子和分子电子结构信息的仪器。它也可用于获得自由基寿命的信息，自由基对于肿瘤生长和/或各种化学反应的开始通常是必不可少的。这些研究将对许多领域产生影响，特别是材料科学和生物化学。
