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

Figure 12

Arrhenius plot of the relaxation times of water measured by various spectroscopic techniques: (i) IXS [14] (from the analysis of the reduced longitudinal moduli discussed in the text, blue stars); (ii) BUVS [34] at  g/cm³ (open circles); (iii) DLS from [35] (red triangles) and (iv) [36] (magenta triangles); (iv) BLS [7] (red squares); and (v) US [37] (yellow diamonds).
