Abstract
Angle-dependent electron-energy-loss measurements of acetylene on Ni(001) are used to deduce molecular symmetry on the surface by consideration of selection rules for vibrational excitation by impact scattering. Chemisorbed acetylene has symmetry with a mirror plane along and a molecular plane tilted relative to the surface.
