Abstract

An analytical theory is presented which permits the calculation of transient effects at widely-separated double channel electrodes. In particular the current response of a downstream (detector) electrode to a potential leap at an upstream (generator) electrode is established and theoretical predictions are found to be in excellent agreement with experiments carried out using the oxidation ofN,N,N′,N′-tetramethyl-phenylenediamine in aqueous solution at a platinum double channel electrode.
