Аннотация:Using molecular simulation, we studied the spectra of longitudinal and transverse excitations of water
(the SPC/E model) and simple liquid (the Lennard-Jones system) along isobars. Comparison of the results for water and simple liquid has shown that the frequency of longitudinal excitations of water demonstrates strong temperature dependence at low temperatures and comes to saturation at high ones. The low temperature regime is in qualitative agreement with the published experimental spectra of longitudinal excitations of water along an isobar. The high temperature regime has not been studied experimentally up to now.
