The THz Spectrum of Density Fluctuations of Water: The Viscoelastic Regime

Figure 10

The reduced longitudinal modulus of water measured by IXS [14] as a function of and at the values indicated in the legend. The centers of the viscoelastic crossover are indicated by horizontal arrows. The straight lines used for the interpolation of the viscoelastic crossover positions are reported (solid lines) together with the curve corresponding to error (dashed line).
