DFT calculations for the adsorption of NO on M2 and MO (M = Rh, Pd) clusters are presented. NO is adsorbed in a bridge position on M 2 (M-NO-M) and in a bent configuration on MO (OM-NO). The adsorption energy is larger for rhodium. The overall charge transfer is a back donation of electrons to the adsorbate which leads to an increase of the NO bond. The adsorption energy is smaller when the metal is oxidized as MO.
