Pulsed voltage perturbation technique

For reversible systems there is no special reason to use these techniques, unless the concentration of the electrochemical active species is too low to allow application of DCP or cyclic voltammetry. For a reversible electrochemical system, the peak potentials in alternating current voltammetry (superimposed sinusoidal voltage perturbation) and in square-wave voltammetry will be equal to the formal potential, i.e., JBp = E However, in differential pulse voltammetry, there is a systematic deviation according to ...
