Acquisition of An Electron Paramagnetic Resonance (EPR) Spectrometer

凭借化学研究仪器和设施：部门多用户仪器计划（CRIF：MU）的这一奖项，Carlito Lebrilla教授和他的同事R。来自加州大学戴维斯分校的大卫布里特将获得一台X波段EPR光谱仪。该提案旨在加强各级的研究培训和教育，特别是在以下研究领域：（a）水分解钴催化剂，（B）二氧化碳的多电子还原，（c）金属蛋白研究，（d）表面和沸石中的功能化材料和催化剂，（e）掺硅纳米颗粒，（f）共轭聚合物共混物中的极化子离域，和（g）具有不寻常配位数和氧化态的过渡金属络合物。EPR光谱仪产生分子和固态材料的几何和电子结构的详细信息。它也可用于获得有关自由基寿命的信息，这些自由基是参与有价值的化学转化以及病理性肿瘤生长起始的短寿命、高反应性物种。这些研究将影响许多领域，从无机和有机分子的合成到新固态材料的开发，再到生物学化合物。从正在进行的研究启发的例子，这个工具将是在本科和研究生水平的研究和教学的一个组成部分。

With this award from the Chemistry Research Instrumentation and Facilities: Departmental Multi-User Instrumentation program (CRIF:MU), Professor Carlito Lebrilla and colleague R. David Britt from University of California at Davis will acquire an X-band EPR spectrometer. The proposal is aimed at enhancing research training and education at all levels, especially in areas of study such as (a) water splitting cobalt catalysts, (b) multielectron reduction of carbon dioxide, (c) studies of metalloproteins, (d) functionalized materials and catalysts in surfaces and zeolites, (e) silicon-doped nanoparticles, (f) polaron delocalization in conjugated polymer blends, and (g) transition metal complexes with uncommon coordination numbers and oxidation states.An EPR spectrometer yields detailed information on the geometric and electronic structure of molecular and solid state materials. It may also be used to obtain information about the lifetimes of free radicals, short-lived, highly reactive species involved in valuable chemical transformations as well as the initiation of pathological tumor growth. These studies will impact a number of areas, from the synthesis of inorganic and organic molecules to the development of new solid state materials to compounds of biological interest. Employing examples inspired from ongoing research, this instrument will be an integral part of research and teaching at the undergraduate and graduate levels.
