Intermolecular proton transport along the hydrogen bond and the dielectric properties of ice crystals

We have attempted here to explain some of the dielectric properties of ice crystals by a concept involving the activated transport of a proton along the hydrogen bond. The choice of the almost symmetrical curve with two minima for a proton in the hydrogen bridge and the rejection of tunnel transport of a proton makes it possible to suggest a theory which explains adequately the dependence of the low frequency dielectric constant on temperature and the phenomenon of the dielectric relaxation of ice. The electrical polarization of an ice crystal according to our model is produced by the defect structure of the ice, the ion pairs, which arises when the proton moves between two neutral water molecules.
This particular model does not involve orientation or Bjerrum defects in the ice structure and raises a doubt as to the necessity of introducing them into explanations of the dielectric properties of ice.
