摘要: 现场电化学一电子自旋共振(SEESR)测量技术是Maki和Geske首次采用的,这使电化学家们能够直接鉴定复杂电极过程中的短寿命中间体.目前这种技术巳得到较大改进,并且用于电化学研究的许多方面,如化学修饰电极、光电化学等,使电化学和电子自旋共振有效地结合起来,国内近几年也开展了这方面的工作.

Abstract: A simultaneous electrochemical-electron spin resonance(SEESR)cell has been designed. It is easily fabricated and operated and can be used for either aqueous or nonaqueous determation.Using this aparatus, the ESR signals were observed for nitrobenzcne anion radicals, produced by constant potential electrolysis of nitrobenzene in acetonitrile media with 0.1M TBAP as electrolyte and in 0.5M KCl aqueous solution respectively. The hyperfine coupling constants of the nitrobenzene anion radical have been estimated which are in accordance with the literature values.
