Abstract

The nuclear resonance scattering of 6324-keV photons from 15N was used to study the tilt angles of N2O molecules adsorbed on graphite. It is shown that for a coverage n=0.8 and 1.3 commensurate √3 × √3 monolayers, at T=12 K, the N2O tilt angles are φ=4°±4° and φ=16°2°, respectively, with respect to the graphite planes. The orientation angle remains nearly the same between 12 K and ∼150 K, while the N2O film passes from a solid to a liquid and then to a gaseous phase.
