Аннотация:We have studied the dependence of the excitation frequency of water along an isochore and an isotherm crossing the region of density anomaly. We have shown that the frequency of longitudinal excitations demonstrated anomalous temperature dependence along the isochore. At the same time the dependence of both longitudinal and transverse excitation frequencies on the density along the isotherm was very modest or even negligible in a fairly wide range of densities. This kind of behavior also seems anomalous in comparison with ordinary liquids.
