Abstract
Using N 1s scanned-energy mode photoelectron diffraction, together with N K-edge near-edge absorption fine structure, the local adsorption site and molecular orientation of 2-methyl-pyridine adsorbed on Cu(110) has been determined and the results are compared with a similar study of pyridine adsorption on the same surface. The molecule is found to bond to the surface through the N atom that occupies a near-atop site. The molecular plane is almost perpendicular to the surface but twisted into an azimuth away from the two principal high-symmetry directions of the surface. The aromatic ring is also tilted within the molecular plane such as to increase the separation of the methyl group away from the surface.
