摘要：

N2 physisorbed on top of a Xe spacer layer on Ag(111) and Pd(111) has been studied by angle-resolved and polarization-dependent UV photoemission. The N2 1-pi-u valence level exhibits a vibrational fine structure due to two multiplets corresponding to the ionic (N2+) and neutral (N2) states. The neutral-state multiplet is explained through hopping of the photohole during photoemission. We show that its intensity is stronger for emission from the in-plane component of 1-pi-u, than for the perpendicular one. This is due to a larger lateral overlap in the former case, as concluded by the observed band formation.
