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.

凭借化学研究仪器和设施 (CRIF) 计划的这一奖项，德克萨斯 A&M 大学将获得一台电子顺磁共振 (EPR) 波谱仪。 EPR 光谱将在 a) 混合价二金属配合物作为生物氢活化过程模型的研究中发挥至关重要的作用； b) 金属-RNA相互作用、金属-肽复合物和双核锰(II)中心； c) 团簇和材料的磁性； d) 四氢蝶呤依赖性酶； e) 硼-硼和硼-碳单电子西格玛键； f)乙酰辅酶A合酶的EPR。电子顺磁共振(EPR)波谱仪是用于获取有关分子的分子和电子结构信息的仪器。它还可用于获取有关自由​​基寿命的信息，自由基对于肿瘤生长和/或各种化学反应的启动通常至关重要。 这些研究将在许多领域产生影响，特别是生物化学和材料科学。
