Non-Aqueous Solutions is a collection of papers presented at the Fourth International Conference on the same subject. One paper presents the application of far- and mid-infra-red, Raman, alkali metal n.m.r. and 35C1 n.m.r. techniques to the study of electrolyte solutions in non-aqueous solvents. The paper notes that spectroscopic techniques can be very useful in the elucidation of the structure of electrolyte solutions. Both the vibrational spectroscopy and particularly the alkali metal n.m.r. are very sensitive probes of the immediate chemical environment of ions in solutions. Another paper points out that the energy change associated with the solvation of ions can be represented as the sum of two energy terms; firstly, from the dielectric polarization of the solvent molecules in the continuous dielectric medium; and secondly, due to specific ion-solvent interactions in the inner solvation shells of the ions. The energy contribution of the latter is minimal but can show comparatively large differences in various types of solvents. Another paper describes the chemistry of solutions in highly associated strong protonic acid solvents, including sulphuric acid, oleums, fluorosulfuric acid, and hydrogen fluoride. Organic chemists, analytical chemists, investigators, and scientists whose works involve physical or inorganic chemistry will find the collection truly beneficial.

Non-Aqueous Solutions — 5 is a collection of lectures presented at the Fifth International Conference on Non-Aqueous Solutions held in Leeds, England, on July 5-9, 1976. The papers explore reactions in non-aqueous solutions as well as the thermodynamic and kinetic properties of non-aqueous solutions. Examples of the use of spectroscopic techniques are presented, and solutions in molten salts are given. Metals in solution and liquid metal solutions are also considered. This book is comprised of 12 chapters and begins with a review of a general scheme which considers the species formed by cation-electron and electron-electron interactions at dilute to moderate concentrations, along with the influence of the solvent and the metal on these interactions. The discussion then shifts to the application of electron spin resonance spectroscopy to the study of solvation; the influence of solvent properties on ligand substitution mechanisms of labile complexes; and the effect of acidity on chemical reactions in molten salts. Subsequent chapters deal with the chemistry of solutions of salts in liquid alkali metals; preferential solvation in kinetics; and the use of non-aqueous solvents for preparation and reactions of nitrogen halogen compounds. Results of Raman spectroscopic studies of non-aqueous solutions and spectroscopic studies of coordination compounds formed in molten salts are also presented. This monograph will be of interest to chemists.
