Abstract

The dynamics of gas–surface interactions has become an area of great interest recently. We present our study of the scattering of vibrationally excited nitric oxide molecules (NO) from a Ag(110) surface. The incident molecules were state-selectively excited to the v = 1, J = 3/2 state by a tunable IR light pulse, and the detection of the scattered molecules was by resonantly enhanced ionization using a tunable UV light pulse, again in a state-specific manner. For the first time known, we were able to detect scattered molecules directly with such a known initial condition and to determine their velocity, angular, and internal energy distributions.
