    • The characteristic time of a votammetry experiment is τ=RT/Fv; it corresponds to the time needed, at the given potential scan rate v, to achieve a 25 mV run of the potential. The half life time θ of the electrogenerated species can be roughly estimated from the amount of chemical reversibility of the wave: θ is close to the τ value associated with the lower scan rate at which the wave exhibits a distinct although small amount of reversibility; another way to estimate θ is to identify it with 10τ′ where τ′ is now associated with the scan rate v′ for which the wave is approximately 50% reversible. Obviously, these two empiric methods only provide orders of magnitude for θ or the pseudo first order rate constant k≈1/θ.
