When self assembled monolayers (SAMs) containing redox centres behave ideally it is a relatively straight forward process to interpret cyclic sweep voltammograms and extract thermodynamic and kinetic information. Unfortunately it is rare that the criteria for ideality are met and other models have to be developed from which to extract information. This review discusses some of the factors which influence the cyclic voltammetry of redox SAMs in particular focussing on how double layer effects influence reversible and irreversible voltammograms. The differences between Butler-Volmer kinetics and Marcus theory kinetics are also discussed
