The angular and velocity distributions of NO scattered from the Pt(111) surface have been measured for a crystal temperature range of 475--1200 K and for an incident beam energy range of 265--1390 K. Both angular and velocity distributions confirm the coexistence of inelastic and trapping-desorption scattering processes. For beams with a kinetic energy of /2k equal to 265 and 615 K, the molecules scattered into angles near the surface normal were found to be equilibrated with the surface for T/sub s/ between 475 and 900 K.
