Rotationally state-selected molecular beams of ND{sub 3} at 0.11 eV are directed at near-normal incidence to a graphite (0001) surface. The relative number density in the scattered beams, measured by photoionization spectroscopy, is found to be two times greater for the incident molecular beam of predominantly {vert bar}{ital JKM}{r angle}={vert bar}222{r angle} rotational states as compared to the {vert bar}111{r angle} beam, implying state-selective trapping.
