Abstract

Dielectric relaxation measurements over the temperature range 273 ≤ T ≤ 360 K of deionized, doubly distilled, water were made and are used to establish transport properties in water. The resonant frequency perturbation and cavity resonance width change are used to establish some dynamical properties ofwater. The nature of the relaxation mechanisms for hydrogen bonding in water systems is explored. Relaxation times for separation and recombination are estimated and used to establish the temperature ranges in which hydrogen bonding dominated in forming polymeric species. The variation in the real ε’ and complex ε” components of the dielectric response E over temperature is assumed to be a consequence of this hydrogen structuring of the aqueous systems and the change of relaxation times for the system produced by these transient structures over temperature.
