Purchase of an EPR Spectrometer for Inorganic Chemistry Research

这份来自化学研究仪器和设施（CRIF）项目的合同将允许塔夫茨大学化学系购买一台电子顺磁共振（EPR）光谱仪。初级教员Elena V. Rybak-Akimova将是该仪器的主要用户，这将有助于她对过渡金属配位化学和选择性氧化还原试剂和催化剂设计的研究。此外，她将研究磁耦合材料；金属离子上有空位的五坐标物质；还有分子镊子。电子顺磁共振波谱仪是一种用于获取分子和分子电子结构信息的仪器。它也可用于获得自由基寿命的信息，自由基对于肿瘤生长和/或各种化学反应的开始通常是必不可少的。

This award from the Chemistry Research Instrumentation and Facilities (CRIF) Program will allow the Chemistry Department at Tufts University to purchase an electron paramagnetic resonance (EPR) spectrometer. Junior faculty Elena V. Rybak-Akimova will be the primary user of this instrument, which will facilitate her studies on transition metal coordination chemistry and the design of selective redox reagents and catalysts. In addition, she will investigate magnetically coupled materials; five-coordinate species with a vacant site at the metal ion; and molecular tweezers. An electron paramagnetic resonance 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.
