Abstract

The dynamics of the 308 nm photochemical reaction between CH₃Br and H coadsorbed on Pt(111) are discussed. Photoinduced dissociative electron attachment of adsorbed CH₃Br produced energetic methyl radicals which abstracted surface H to give desorbing methane photoproduct. Photoproduct angular and translational energy distributions were derived from time-of-flight spectra to a quadrupole mass spectrometer following pulsed excimer laser irradiation of the surface.
