Abstract
Lattice modes have been observed at 37 and 81 cm−1 in Raman spectra of orthorhombic polyoxymethylene. The normal modes of the orthorhombic polyoxymethylene crystal have been calculated and used to assign the lattice modes. The intermolecular potential has been evaluated and used to compute the dispersion curves and frequency distribution of the crystal. The calculated frequency distribution has been compared to that observed experimentally by inelastic neutron scattering.Keywords
