We report on the scattering of supersonic NO molecules from a diamond (111) surface. Using state selective laser techniques combined with mass selective quadrupole measurements, we observe two novel features in the molecule--surface interaction: first, a scattering behavior which is dependent on the direction of the incoming molecules; and second, surface residence times that are unusually long, but temperature independent. The former observation can be traced back to the topography of the unreconstructed diamond (111) surface, the latter one can be understood when a temporary function of a metastable surface--molecule complex is assumed.
