Thin-layer electrochemical resonance-Raman measurement for complex electrode reactions
Abstract
Resonance-Raman spectroscopy in conjugation with electrochemical measurements clarify that the complex voltammetric response of 2,3,5,6-tetrachloro-1,4-benzo-quinone (TCQ) in the presence of Mg2+ is due to the further reduction of the intermediate ion pair, Mg2+·TCQ˙–, to the dianion pair, Mg2+·TCQ2–.
