<jats:p>The Raman scattering in crystalline polyethylene, deuterated polyethylene, and n-paraffins has been investigated as a function of temperature. Crystal-field splitting of the A1G methylene bending mode observed at room temperature increases at − 160°C in both polyethylene and deuterated polyethylene. No splitting of the B2G skeletal stretching mode and the B3G methylene twisting modes in polyethylene is observed at room temperature, but the two components of the space group fundamental are resolved at − 160°C. Similarly, splitting of the B2G methylene wagging mode in deuterated polyethylene is observed at − 160°C but not at room temperature. The observed crystal-field splittings are discussed in terms of splittings calculated from repulsive forces between hydrogen atoms on neighboring chains in the polyethylene crystal.</jats:p>
