Molecular Mechanisms of Conduction and Polarization in Water Vapor, Liquid Water, and Ice.
Abstract
After a short review of the pertinent prehistory, the investigation starts with water vapor. Thermal ionization requires formation of special association complexes and their dissociation by infrared vibrations. The corresponding process occurs in water and is being analyzed in detail. Proton tunneling appears interdicted by a 6proton polaron6 effect. The dielectric polarization for water and for ice are of very different origin as their temperature dependence clarifies; the former is correlated to the break-up of a glaseous tetrahedral structure, the latter is initiated by a quantum transition. Ice proves not to be a proton semi-conductor; perfect ice crystals seem to be insulators. The results of previous observers have been falsified by multicrystallinity and insufficient time scales of observation. (Author-PL)
