A model Hamiltonian to describe adsorbate-mediated electron transfer is proposed and analyzed for the (electrochem.) currents. This Hamiltonian differs fundamentally from the ones used earlier (cf. Schmickler 1980, 1982). Three situations are treated, viz., (1) a lone adsorbate picture; (2) presence of an inactive neighboring adsorbate; and (3) electrostatic effects due to an adsorbate lattice. In all 3 cases, the mediation is via a single adsorbate only. Several limiting cases are considered and related to the earlier results of Marcus and Schmickler.
