The lattice dynamics of the molecular crystal N 2 O is treated throughout the Brillouin zone within the framework of classical harmonic approximation. By using the Kohin type potential, dispersion curves, density of states, and heat capacity at low temperatures are obtained. The results are in good agreement with available experimental data. It is also shown that the lattice frequencies of the isomorphous crystal CO 2 calculated by using the same potential agree well with neutron scattering data.
