The lattice dynamics method in the quasi-harmonic approximation has been used to study the thermal expansion of C3H8-, CH4-, CF4-, CO2-, Xe-, and N2-hydrates over a wide temperature range. By accounting for the anharmonic nature of interactions inside the hydrate, the model shows good agreement with...
