We will present recent results from our study of the dissociation of vibrational-state-selected CO@sub2@ on Ni(100). Previous studies@footnote 1@ have shown that the reaction is enhanced by increasing the average thermal vibrational population of the CO@sub 2@ molecules. In our study, infrared laser excitation of CO@sub 2@ in a supersonic molecular beam produces molecules with a well-defined translational energy in a particular vibrational and rotational state. Quantifying the efficacy of energy in a specific rovibrational coordinate reveals key aspects of the potential energy surface governing the interaction. @FootnoteText@ @footnote 1@ M.P. d'Evelyn, A.V.
