Abstract
Collision-induced dissociation (CID) of highly excited NO2 in the mixe d 2A1/B-2(2) electronic system has been observed for well characterize d MgO(100) surfaces with parent and product angular resolution at vari ous internal energies. NO state distributions were probed by two-photo n, two-frequency ionization, and its yield was found to track the NO2 absorption spectrum, confirming the CID mechanism. The angular depende nce of the NO state distribution indicates that CID occurs following d irect inelastic scattering rather than trapping-desorption.
