Acquisition of an Electron Spin Resonance Facility (Chemistry)

电子自旋共振（ESR）光谱是研究含有未配对电子的分子的一项关键技术。在光化学、电化学和热刺激下对无机、有机金属和有机材料进行ESR测量，可以了解任何其他技术都无法实现的化学结构。ESR仪器的获得提高了化学家开展前沿研究的能力。麻省理工学院化学系和Francis Bitter国家磁体实验室将使用化学共享仪器计划的这笔资金来帮助购买ESR光谱仪。将加强化学各领域的研究，包括：1)多铁在化学和生物学中的中心作用2)细胞色素P450和固氮生物化学3)镍产甲烷作用4)高氧化态钼钨二氮配合物5)放射性药物和相关的放射性化学；6)有机金属分子和多组分氧化还原试剂的ESR研究；7)铁硫蛋白位点类似物的电子学和磁性

Electron Spin Resonance (ESR) spectroscopy is a key technique for the study of molecules that contain an unpaired electron. ESR measurements on inorganic, organometallic and organic materials under photochemical, electrochemical and thermal stimulation lead to an understanding of chemical structure that is unattainable by any other technique. The acquisition of ESR instrumentation enhances the ability of chemists to carry out frontier research. The Department of Chemistry of the Massachusetts Institute of Technology and the Francis Bitter National Magnet Laboratory will use this award from the Chemistry Shared Instrumentation Program to aid in the purchase of an ESR spectrometer. Studies in various areas of chemistry will be enhanced and include the following: 1) Polyiron centers in chemistry and biology 2) Cytochrome P450 and nitrogen fixation biochemistry 3) Nickel methanogenisis 4) High oxidation stat molybdenum and tungsten dinitrogen complexes 5) Technetium radiopharmaceuticals and related technetium chemistry 6) ESR studies of organometallic molecules and multicomponent redox reagents 7) Electronics and magnetic properties of iron-sulfur protein site analogues
