Abstract

A nuclear resonance photon scattering (NRPS) study of the N2-graphite system yields values for the out-of-plane tilt angle of N2 molecules versus T at a coverage of 1.05 monolayers which are in good agreement with molecular-dynamic-simulation predictions. The zero-point energies of the out-of-plane vibrational and librational motions of the N2 molecule with respect to the adsorbing graphite surface are determined. The N2 molecules were found to tilt towards the graphite surface even at temperatures as high as 160 K.
