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.
