The photodissociation of methyl nitrite in the molecular beam has been studied by laser irradiation at 348ndash;364 nm. The NO photofragments were analyzed by MPI analysis in a onehyphen;color experiment. The translational energy distribution for the photofragment indicates that there are two distinct paths by which CH3O and NO radicals are produced; one is a onehyphen;photon dissociation, and the other is a twohyphen;photon dissociation. The angular distribution of fragment intensities peaks in a direction orthogonal to the electric vector of the photolysis light indicating that the transition moments for both the first and the second onehyphen;photon absorptions lie perpendicular to the Ondash;N bond that breaks.
