Identification of structural relaxation in the dielectric response of water [PDF]

Phys. Rev. Lett. 116, 237601 (2016), 2016
One century ago pioneering dielectric results obtained for water and n-alcohols triggered the advent of molecular rotation diffusion theory considered by Debye to describe the primary dielectric absorption in these liquids. Comparing dielectric, viscoelastic, and light scattering results we unambiguously demonstrate that the structural relaxation ...
