Query: Diffusion-Oscillatory Dynamics in Liquid Water on Data of Dielectric
  Spectroscopy   When analyzing the broadband absorption spectrum of liquid water (10^10 -
10^13 Hz), we find its relaxation-resonance features to be an indication of
Frenkel's translation-oscillation motion of particles, which is fundamentally
inherent to liquids. We have developed a model of water structure, of which the
dynamics is due to diffusion of particles, neutral H2O molecules and H3O+ and
OH- ions - with their periodic localizations and mutual transformations. This
model establishes for the first time a link between the dc conductivity, the
Debye and the high frequency sub-Debye relaxations and the infrared absorption
peak at 180 cm-1. The model reveals the characteristic times of the
relaxations, 50 ps and 3 ps, as the lifetimes of water molecules and water
ions, respectively. The model sheds light on the anomalous mobility of a proton
and casts doubt on the long lifetime of a water molecule, 10 hours, commonly
associated with autoionization.
