N2 - This chapter discusses the intrinsic and adsorbate-modified vibrations of the copper(110) surface. High resolution electron energy loss spectroscopy (HREELS) has been used to study a surface phonon of a clean and adsorbate covered Cu(110) surface. The chapter studies the changes in energy, intensity, and width of the surface phonon on Cu(110) as a function of the order and concentration of adsorbed CO, O2, H2, COS and H2S to probe the nature of this type of phonon. The intrinsic properties of the phonon and bonding information that is implied from the phonon behavior upon adsorption are discussed. Surface phonon measurements reveal force constants of surface bonds that determine the surface Debye temperature and govern the kinetics of processes at interfaces. Reconstruction of a clean surface can occur when surface phonon energies differ from bulk phonon energies. Adsorbates can induce surface phonon softening that will drive reconstruction. Binding sites of adsorbates can be determined by the symmetry of surface phonons.
