Description
Collision-induced dissociation (CID) of highly excited NO2 in the mixed 2Al1/2B2 electronic manifold is observed for collisions with a well-characterized MgO(100) surface. The incident NO2 molecules, possessing a selected amount of internal and translational energy, approach the surface from a well-defined angle of incidence. The angle-resolved NO product state distribution is probed by resonance enhanced multi-photon ionization. The NO yield correlates with the NO2 absorption spectrum, confirming the CID mechanism. At NO2 incident angles ≤45 degrees, the angular dependence of the NO product state distribution indicates that CID occurs following direct inelastic scattering rather than trapping-desorption. The mechanism for more grazing collisions will be addressed and similar experiments are planned using the Al2O3(1120) surface
