ABSTRACT
The low energy vibrations of NH3 and CO molecules adsorbed on Fe(110) have been investigated with inelastic He-atom scattering. For ammonia an energy loss of 10 meV was observed in the time-of-flight spectra and is assigned to the frustrated translations. Previously, this mode had only been observed for adsorbed CO molecules. For CO on Fe(110) the energy of the frustrated translations is 4.6 meV and the observed linewidth is smaller than 0.6 meV.
