Abstract
State-resolved characterization is carried out for a photodissociation reaction in the monolayer region on a metal surface, . Contrary to common expectation based on quenching rates, both translational and rotational energies of CO (g) from monolayer photodissociation are much higher than those from multilayers. We take this as evidence for concerted reaction dynamics on the surface: The high exothermicity in the Cl-Ag bond formation on the surface exerts part of the energy to the Cl-CO coordinate, leading to higher energies in CO (g).

- The fluxes of CO were determined in separate experiments at fixed probe laser wavelengths. The flux was constant for multilayer, but decreased with the extent of photolysis for monolayer. The monolayer spectrum was obtained in ten measurements, each starting with a freshly prepared surface and ending with more than 50% of remaining on the surface. These measurements were for small overlapping wavelength intervals, with each spectrum normalized to the CO flux. Within experimental uncertainties, the flux-normalized spectrum was independent of the extent of photolysis.
