Abstract
The azimuthal variations in the photoemission cross section for the molecular orbital of N adsorbed on Ni(111) are used to identify the angular orientation of the adsorbed molecules. From comparison of experiment and theory, it is possible to determine the NH-bond directions relative to the substrate. In addition, it is found that the observed strong azimuthal anisotropy comes mainly from direct interference of emissions from the molecular orbital rather than from backscattering off the substrate.
