Synergistic effects of the surface magnetic field (SMF) and the laser on the predissociation of adsorbed diatomic molecules are studied theoretically. It is observed that the couplings between the laserhyphen;dressed and SMFhyphen;split molecular potentials create interference effects within the nuclear motion. These effects can cause enhancement or diminution in predissociation rate as compared to the analogous gashyphen;phase laserhyphen;induced process. SMF/laserhyphen;induced predissociation rates for a few specific examples are derived using the semiclassicalShyphen;matrix formalism and results for the enchancement and diminution are discussed along with their dependence on laser power densities.
