Upgrade of the EPR Facility at Texas A&M University

得克萨斯农工大学将获得化学研究仪器和设施(CRIF)计划颁发的这一奖项，从而获得电子顺磁共振(EPR)光谱仪。电子顺磁共振波谱将在以下方面发挥重要作用：a)混价双金属络合物作为生物氢活化过程的模型；b)金属-RNA相互作用、金属-多肽络合物和双核锰(II)中心；c)簇合物和材料的磁性；d)四氢蝶呤依赖的酶；e)硼-硼和硼-碳单电子sigma键；f)乙酰辅酶A合成酶的EPR。电子顺磁共振(EPR)光谱仪是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, Texas A&M University will acquire an Electron Paramagnetic Resonance (EPR) Spectrometer. EPR spectroscopy will play a vital role in the studies of a) mixed-valence dimetallic complexes as models for biological hydrogen activation processes; b) metal-RNA interactions, metal-peptide complexes and dinuclear manganese (II) centers; c) the magnetic properties of clusters and materials; d) tetrahydropterin-dependent enzymes; e) boron-boron and boron-carbon one-electron sigma bonds; and f) EPR of acetyl-CoA synthase.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.
