The Chemical Physics Of Solvation

The importance of solvation as a concept which covers quite generally the interactions between a molecular solute particle and a macroscopic body of surrounding solvent is well recognized. Solvation plays a major role in the distribution of elements in the geo- and hydrosphere, and most chemical and biological processes involve solvated reactants and products, the electronic and molecular structure of which are strongly determined by solvation. This three-volume monograph has been written collectively by 50 authors from 14 countries who are specialists in different areas of solvation science. Part A deals with the theory of solvation; Part B is entirely devoted to spectroscopy of solvation; and Part C covers solvation phenomena in specific physical, chemical and biological systems. The volumes will be an invaluable reference source for physicists, physical chemists and biophysicists undertaking investigations into the diversified and fascinating areas of the physics and chemical physics of solvation at postgraduate and professional research levels.

This book covers the theory and applications of continuum solvation models. The main focus is on the quantum-mechanical version of these models, but classical approaches and combined or hybrid techniques are also discussed. Devoted to solvation models in which reviews of the theory, the computational implementation Solvation continuum models are treated using the different points of view from experts belonging to different research fields Can be read at two levels: one, more introductive, and the other, more detailed (and more technical), on specific physical and numerical aspects involved in each issue and/or application Possible limitations or incompleteness of models is pointed out with, if possible, indications of future developments Four-colour representation of the computational modeling throughout.

This book deals with a subject that has been studied since the beginning of physical chemistry. Despite the thousands of articles and scores of books devoted to solvation thermodynamics, I feel that some fundamen tal and well-established concepts underlying the traditional approach to this subject are not satisfactory and need revision. The main reason for this need is that solvation thermodynamics has traditionally been treated in the context of classical (macroscopic) ther modynamics alone. However, solvation is inherently a molecular pro cess, dependent upon local rather than macroscopic properties of the system. Therefore, the starting point should be based on statistical mechanical methods. For many years it has been believed that certain thermodynamic quantities, such as the standard free energy (or enthalpy or entropy) of solution, may be used as measures of the corresponding functions of solvation of a given solute in a given solvent. I first challenged this notion in a paper published in 1978 based on analysis at the molecular level. During the past ten years, I have introduced several new quantities which, in my opinion, should replace the conventional measures of solvation thermodynamics. To avoid confusing the new quantities with those referred to conventionally in the literature as standard quantities of solvation, I called these "nonconventional," "generalized," and "local" standard quantities and attempted to point out the advantages of these new quantities over the conventional ones.

This book highlights the latest advances and outlines future trends in aqueous solvation studies from the perspective of hydrogen bond transition by charge injection, which reconciles the solvation dynamics, molecular nonbond interactions, and the extraordinary functionalities of various solutes on the solution bond network and properties. Focus is given on ionic and dipolar electrostatic polarization, O:H nonbond interaction, anti-HB and super-HB repulsion, and solute-solute interactions. Its target audience includes researchers, scientists, and engineers in chemistry, physics, surface and interface science, materials science and engineering.
