The purpose fo this book is to present a comprehensive account of the physical concepts and theoretical approaches developed for the study of the dynamical properties of liquids (or more generally, of high-density fluids) at a microscopic level. After a discussion of the basic dynamical phenomena to be interupted, as well as of the various experimental probes, the book gradually exposes the reader to the sophisticated theoretical techniques needed for a satisfactory account of both single particle and coleective motions. The complications are faced in a stepwise fashion, with special attention to the physical content of the results. As a result of the progress achieved in the last decade, in the end a satisfactory understanding of most of the phenomena characterizing this fascinating field emerges.

An Introduction to the Liquid State focuses on the atomic motions and positions of liquids. Particularly given importance in this book are internal motion of molecules as a whole and the motion of atoms in a monatomic liquid. Divided into 16 chapters, the book opens by outlining the general properties of liquids, including a comparison of liquid argon and liquid sodium, discussions on theories and methods of studying the liquid state, and thermodynamic relationships. The book proceeds by defining the molecular distribution functions and equation of state, the potential function for non-conducting liquids and metals, and measurement of pair distribution function. Numerical analyses and representations are provided to simplify the functions of equations. The book discusses equilibrium properties wherein calculations on the state of gases and fluids are presented. The text also underlines space and time dependent correlation functions. Given emphasis in this part are neutron scattering, electromagnetic radiation, and various radiation scattering techniques. Other concerns discussed are diffusion and single particle motion, velocity of correlation function, diffusion and viscosity coefficients, liquid-gas critical point, and a comparison of classical and quantum liquids. The selection is a valuable source of information for readers wanting to study the composition and reactions of liquids.

Physical Chemistry: An Advanced Treatise: Liquid State, Volume VIIIA, deals with simple liquids because the theory is most developed for these liquids. The purpose of this treatise is to present a comprehensive treatment of physical chemistry for advanced students and investigators in a reasonably small number of volumes. An attempt has been made to include all important topics in physical chemistry together with borderline subjects which are of particular interest and importance. The book contains six chapters and begins with an introduction to intermolecular pair potential-energy functions, the principle of corresponding states, and the equation of state for dense liquids. It then discusses the static and dynamic structure of liquids, followed by separate chapters on the four main techniques in the theory of liquids: simulation studies, integral equation methods, lattice theories, and perturbation theories.

Topics covered include basic theory, procedural aspects of implementation of basic equations on the computer and a review of recent applications in emerging areas of research.
