Abstract

Solid CO2 phase I was studied using the pressure-constant NPT Monte Carlo simulation and the Kihara core potential in the temperature range below 194 K and the pressure range below 10 GPa. At a pressure of 1 bar, the temperature dependence of the calculated lattice constant agreed reasonably well with experiment. It was found that the random distribution of molecular orientations due to temperature gave a significant contribution to the increase in the lattice constant. At high pressure, the pressure dependence of the lattice constant also agreed well with experiment.
