Summary: The rate constants for the dimerization of the reduced products of methyl viologen dication (MV2+) of the processes (a) methyl viologen cation radical (MV+*), (EQUATION) and (EQUATION) and (b) methyl viologen neutral (MV), (EQUATION) and (EQUATION) were obtained through linear scan- / cyclic-voltammetry and the use of Olmstead-Hamilton-Nicholson theory.
