The vibration spectrum of surface phonons for ordered phases of ethane monolayers adsorbed on graphite is investigated using different potential functions. The average heat motion amplitudes of molecules adlayer, effective molecular polarizabilities, and their derivatives with respect to external coordinates, which determine Raman spectra intensities as well as the section of one‐phonon inelastic neutron scattering from the surface are calculated taking into account the ethane‐substrate dynamic interaction. The last results are compared with experimental ones.
