The Purchase of an Electron Paramagnetic Resonance Spectrometer

电子顺磁共振(EPR)谱使化学家能够对含有未配对电子的材料(顺磁化合物)进行极其精确、高分辨率的研究。这样的研究揭示了任何其他技术无法获得的分子结构信息。德克萨斯A&M大学化学系将利用化学仪器计划的这一奖项帮助获得EPR光谱仪。此次收购将加强的化学研究领域包括：1)表面化学和多相催化2)富电子过渡金属氢化物反应中的自由基物种，酰基和硫醇酸盐3)研究酶中金属络合物的新方法4)铜(II)双-2‘2’-联吡啶胺作为铜蛋白活性中心模型的结构研究5)氨基和氨阳离子自由基6)定向过渡金属化合物的单晶研究。

Electron Paramagnetic Resonance (EPR) spectroscopy allows chemists to conduct extremely precise, high resolution studies on materials containing unpaired electrons (paramagnetic compounds). Such studies reveal information on molecular structure that is unavailable by any other technique. The Department of Chemistry at Texas A & M University will use this award from the Chemical Instrumentation Program to help acquire an EPR spectrometer. Among the areas of chemical research that will be enhanced by the acquisition are included the following: 1) Surface chemistry and heterogeneous catalysis 2) Radical species in reactions of electron-rich transition metal hydrides, acyls and thiolates 3) Novel approaches to the study of metal complexes in enzymes 4) Stuctural studies of copper (II) bis-2'2'-dipyridylamines as models for active centers in copper proteins 5) Aminyl radicals and aminium cation radicals 6) Oriented single crystal studies of transition metal compounds.
