摘要：

The high-frequency sound velocity v(infinity) of liquid water has been determined to densities of 1.37 g/cm(3) by inelastic x-ray scattering. In comparison to the hydrodynamic sound velocity v(0) the increase of v(infinity) with density is substantially less pronounced, indicating that, at high density, the hydrogen-bond network is decreasingly relevant to the physical properties of liquid water. Furthermore, we observe an anomaly in v(infinity) at densities around 1.12 g/cm(3), contrasting the smooth density evolution of v(0).
