he theoretical model presented in Part 1 is employed to simulate and fit experimental probe beam deflection (PBD) data of FeðCNÞ 36=FeðCNÞ46 and Fe3+/Fe2+ couples collected under voltammetric conditions. The dependence of beam deviation on the diffusion coefficients and on the charges of Involved species is described. The fit of voltammetric curves was performed to get the values for the standard potential of each system as well as diffusion coefficients of electroactive species. The data were then employed to fit a set of experimental voltadeflectometric profiles collected at different beam-electrode distances. The least-squares Simplex algorithm was employed to fit proposed functions to experimental data. The data obtained from the fitted voltadeflectometric curves were consistent with values previously reported for chronodeflectometry profiles, supporting the hypothesis that the refraction index not only
