The topics covered in this book provide a qualitative and sometimes quantitative classic description of the wide-band 0-THz dielectric spectra of polar liquids, molecular libration-rotation (which is the reason for dielectric loss and absorption of electromagnetic waves), simple molecular models differing by the intermolecular-potential profiles, and present a comparison between the theoretical and experimental dependencies and derivation of the main results. A new feature is the application of a number of analytical models to different substances, including strongly absorbing nonassociating liquids, liquid water, water bound by macromolecules, and gas-like liquids. The presentation of the theory in this book is also new. It is based on the dynamic method in which the Brownian reorientations are considered implicitly, without direct solution of stochastic equations. This approach simplifies the theory. Senior students and experimentalists will find many of the results valuable.

Russian contributors provide a synthesis of ideas drawn from dielectric, magnetic and elastic relaxation. Divided into three sections, the book commences with dielectric and related processes in simple liquids. Part two deals with the structure and dielectric relaxation of aqueous solutions. Lastly, it addresses magnetic and dielectric relaxation in liquid crystals and elastic relaxation in orientable polymers.

Theory of Electric Polarization, Volume II: Dielectrics in Time-Dependent Fields focuses on the processes, reactions, and principles involved in the application of dielectrics in time-dependent fields, as well as the Kerr effect, statistical mechanics, and polarization. The publication first examines the phenomenological theory of linear dielectrics in time-dependent fields; empirical description of dielectric relaxation; and the relationship between macroscopic and molecular dielectric relaxation behavior. Concerns cover the relationship between macroscopic and microscopic correlation functions; statistical mechanics of linear dissipative systems and the relationship between response functions and correlation functions; superpositions of distribution functions; and the use of complex dielectric constant in problems with time-dependent field sources. The book then ponders on the dipole correlation function, polarization in the infrared and optical frequency range, and the Kerr effect and related phenomena. Discussions focus on the Kerr effect in condensed systems, extensions of the Kerr effect, extrapolation of the refractive index to infinite wavelength, results obtained from computer simulations, rotational diffusion, and general aspects of molecular reorientation. The manuscript tackles the dielectric properties of molecular solids and liquid crystals and experimental determination of permanent dipole and quadrupole moments. The text is a valuable source of data for researchers interested in the application of dielectrics in time-dependent fields.
