Abstract
A theory of the transient response of an electrochemical system to a p otential-step perturbation (chronoamperometry) is developed using the Sumi-Marcus formalism. Depending on the value of the rate constant, th e current response can be diffusional or exponential. The rate constan t obtained includes strongly nonadiabatic and solvent-controlled limit ing cases. A new method of determining the range of electron transfer adiabacity is proposed.
