Purchase of an EPR Spectrometer for Inorganic Chemistry Research

化学研究仪器和设施(CRIF)计划授予的这一奖项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，这将有助于她研究过渡金属配位化学以及选择性氧化还原试剂和催化剂的设计。此外，她还将研究磁性耦合材料；金属离子上有空位的五配位物种；以及分子镊子。电子顺磁共振光谱仪是一种用于获取分子的分子和电子结构信息的仪器。它还可以用来获得有关自由基寿命的信息，这些自由基通常是启动肿瘤生长和/或各种化学反应所必需的。

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.
