A detailed analysis of experimentally obtained temperature-dependent gas-phase kinetic data for the oxygen and carbon monoxide adsorption on small anionic gold (Au-n(-), n = 1-3), silver (Ag-n(-), n = 1-5), and binary silver-gold (AgnAum-, n + m = 2, 3) clusters is presented. The Lindemann energy transfer model in conjunction with statistical unimolecular reaction rate theory is employed to determine the bond dissociation energies E-0 of the observed metal cluster complexes with O-2 and CO. The accuracy limits of the obtained binding energies are evaluated by applying different transition-state models. The assumptions involved in the data evaluation procedure as well as possible sources of error are discussed. The thus-derived binding energies of O-2 to pure silver and binary silver-gold cluster anions are generally in excellent agreement with previously reported theoretical values. In marked contrast, the binding energies of O-2 and CO to Au-2(-) and Au-3(-) determined via temperature-dependent reaction kinetics are consistently lower than the theoretically predicted values.
