摘要：

The far-infrared spectra of polycrystalline ethylene were recorded at various temperatures between 65° and 20°K and at 8°K. Two bands were observed both for ethylene and ethylene-d4. The frequency ratio of corresponding bands in ethylene and deuteroethylene prove that these absorption bands are due to translational lattice modes. Absolute intensities of the observed bands in ethylene were measured. The frequencies of the translational lattice modes were calculated for two different models of intermolecular forces, i.e., center-to-center Lennard-Jones potential and atom-atom repulsion potential.
