The rate constants for the dimerization of the reduced products of methyl viologen dication (MV2+) of the processes (a) methyl viologen cation radical (MV+•), (MV2+ MV+•) and 2MV+• (MV+•)2 and (b) methyl viologen neutral (MV), (MV+• MV) and 2MV (MV)2 were obtained through linear scan- / cyclic- voltammetry and the use of Olmstead-Hamilton-Nicholson theory. The rate constants for the two dimerization processes are reported here. Rate constant for the dimerization process (b) above, of the novel species methyl viologen neutral is being reported first time.
