The theory of cyclic voltammetry of redox adsorbates based on the nonadiabatic kinetic models of Levich and Dogonadze (GMLD kinetics) is re-examined. It is shown that if generalized predictions of cyclic voltammetric behavior are sought, the model is applicable only over a small range of reorganization energies. It is well-known that at high reorganization energies Tafel plots simulated using both Butler−Volmer and GMLD kinetics give similar results; however, cyclic voltammograms simulated from GMLD kinetics at high reorganization energies do not reduce to the generalized Butler−Volmer model for cyclic voltammogram of redox adsorbates derived by Laviron (J. Electroanal. Chem. 1979, 101, 19). Two methods of solution to the cyclic voltammogram equation are considered: a finite difference numerical solution and an analytical approximation. The analytical approximation enables a more rapid simulation of cyclic voltammograms. Methods for applying the model to real systems are suggested which include an equati...
