Phonon spectra are obtained using inelastic neutron scattering by polycrystals of the Chevrel-phase superconductors SnMo/sub 6/S/sub 8/, PbMo/sub 6/S/sub 8/, Mo/sub 6/Se/sub 8/, and Pb/sub 1/./sub 2/Mo/sub 6/Se/sub 8/. Modes associated primarily with Sn (or Pb) atomic displacements are clearly identified. Acoustic softening on cooling is noted for SnMo/sub 6/S/sub 8/. Anharmonicity and the superconductivity are discussed utilizing the molecular-crystal concept.
