Abstract
The theory and application of square wave voltammetry to surface-confined quasi-reversible redox molecules (Ox+ne - =Red) is described. Theoretical voltammograms were calculated based on the following assumptions: (1) stable redox states ; (2) monolayer or less surface coverage; (3) equivalent surface sites and adsorbates; (4) non adsorbate-adsorbate interactions; (5) no diffusional contributions to the current; and (6) Bulter-Volmer electrode kinetics. A working curve strategy based on peak separation between positive-scan and negative-scan net current voltammograms was developed to facilitate the semiquantative determination of electron-transfer rate constants
