With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at the University of Idaho will acquire an Electron-spin Resonance Spectrometer. The new instrument will support the research in the following areas: a) characterization of ansa-chromocene complexes; b) investigations of protein-small molecule interactions; c) studies on the coordination geometry of nitrosyl ligands in photoexcited transition metal complexes; d) molecular-level basis for antioxidant mechanisms of flavonoids; e) investigation of Cu sorption mechanism on clay minerals; and f) properties of Pdtc as a bioremediation agent. 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 that 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 biochemistry.

有了化学研究仪器和设施（CRIF）计划的这一奖项，爱达荷州大学化学系将获得一台电子自旋共振光谱仪。新仪器将支持以下领域的研究：a）柄型二茂铬配合物的表征; B）蛋白质-小分子相互作用的研究; c）光激发过渡金属配合物中亚硝酰基配体的配位几何研究; d）黄酮类化合物抗氧化机理的分子水平基础; e）粘土矿物对铜吸附机理的研究;和f）Pdtc作为生物修复剂的性质。 电子顺磁共振（EPR）光谱仪是一种用于获得分子和分子电子结构信息的仪器。它还可以用来获得有关自由基的寿命的信息，这些自由基通常是肿瘤生长和/或各种化学反应的起始所必需的。这些研究将在一些领域产生影响，特别是生物化学。
