Theoretical and experimental study of hydrogen bonded liquids with water as an example

Abstract Hydrogen bond dynamics have been studied and methods for evaluation of probability and relaxation time for hydrogen bond network are discussed. Dielectric relaxation time has been calculated by using a diagonalization procedure for obtaining eigen values (Inverse of relaxation time) of a master equation framed on the basis of Fokker–Planck equations. Microwave cavity spectrometer has been described to make measurements of relaxation time. Slater's perturbation equations are given for the analysis of the data. A comparison of theoretical and experimental data shows that there is a need for improvements in the theoretical model and experimental techniques to provide exact information about structural properties of water. The influence of intense external fields and effects of non-linearity for simple unassociated liquids in their three dimensions and one dimension have been described respectively.
