| Popis: | Configurations of the molecules on the wall of a vacancy, formed by removing a central and its first and second nearest-neighbor (NN) molecules in solid CO2 with the Pa3 structure, were calculated by the Monte Carlo simulation technique at T = 0, 100, and 200 K and a nominal pressure of P = 1 bar. It was found that the deviations of both the center-of-mass and the orientational coordinates of the molecules from the unperturbed coordinates had a three-fold symmetry about a body diagonal axis of the crystal. It was also found that a single CO2 molecule, initially placed in the center of the vacancy, was stabilized at a position close to the vacancy wall.
