Molecular-dynamics calculation of the vibrational densities of states and infrared absorption of crystalline rare-gas mixtures.

Relaxations around defect sites, vibrational local densities of states, and absolute infrared absorptions are computed on the twelve possible crystal mixtures of Ne, Ar, Kr, and Xe in the highly diluted limit, using molecular dynamics. We found that the lattice deformation does not decay uniformly with the distance from the impurity, and that it plays an important role in determining the effective interactions. Vibrational local densities of states show that, except for Ar-Kr mixtures, light impurities give resonant bands and heavy impurities produce localized modes. Infrared-absorption calculations show a good agreement with the experimental data. The possibility of refining mixed-rare-gas interaction potentials by use of these systems as probes is discussed.
