Abstract
The interaction of a beam of state selected and oriented molecules with 1 ML of Cs on Pt(111) is studied by means of exoelectron emission. While the immediate emission is absent for the impact of ground-state molecules it is present when the molecules are in the first excited vibrational bending mode. The observed orientational anisotropy agrees with a theory that includes the molecular orientation. The results can be explained in a picture where approaches the surface with the O end and where—after harpooning—an exoelectron is emitted.
