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

Figure 7

The spectrum of polycrystalline ice Ih measured in [11] at some selected s (open circles) is compared with corresponding best fit model line-shapes. The letters “T” and “L” label, respectively, the transverse and longitudinal peaks, while the suffixes “S” and “AS” indicate, respectively, the “Stokes” and “anti-Stokes” components.
