Abstract
The vibrational properties of models of vitreous silica constructed by molecular-dynamics simulation with different interatomic potentials h ave been investigated. The static and dynamical structure factors of t he model systems are in good agreement with experimental data. Partial and total vibrational densities of states are presented. The characte ristics of vibrational modes in different frequency ranges are investi gated using a mode-projection technique.
