On the other hand, only apparent equilibrium constants depending on concentrations of an acid and a radical could be obtained from electrochemical measurements at a mercury electrode. Significant differences in reaction stoichiometry and in order of magnitudes of disproportionation constants found under spectroscopic and electrochemical conditions were discussed in terms of an influence of the electric field in the double layer on the distribution of different associates formed by verdazyl species with acids.
