Hydrogen-Bonded Solvent Systems, edited by A. K. Covington and P. Jones, Taylor and Francis, London, 1968, xiv+ 354 pages, £6 or $14.50. To mark the retirement of Lord Wynne-Jones from the chair of physical chemistry at Newcastle, which he had Occupied for 21 years, his colleagues had the excellent idea of organising two symposia which together with the Faraday Society Discussion in April, 1968 cover the broad fields of chemistry to which he has made notable contributions. This volume is the record of the first of these symposia, held in January, 1968. It followed the pattern of the Faraday Society Discussions, as does the publication, with the welcome addition of a subject index. In particular, besides the papers, there is a record of the discussion which was opened in characteristic fashion by Lord Wynne-Jones himself. In the introductory paper, Everett outlines Wynne-Jones' scientific career giving particular attention to their joint work on acid strength and its connection with the structure of the solvent. There are five review lectures : Walrafen describes new experiments on the Raman spectrum of water using an argon-ion laser. These are used to support a broken hydrogen-bond model of water. Franks discusses the properties of mixtures of water and organic compounds in terms of their structure. Bates gives a large quantity of quantitative data on transfer free energies for a variety of mixed solvent systems in a most useful article. Stein's review of equilibrium and kinetic properties of the solvated electron and atomic hydrogen in water is also valuable although it fails to convey the spellbinding brilliance of the original lecture. Hyne gives results for heat capacities and volumes of activation for solvolysis reactions in aqueous +non-aqueous mixtures. It must be admitted that these thorough studies do not advance our understanding in proportion to the amount of experimental effort involved, though it is to be hoped that they will form the foundations for improved theory in the future. The eighteen invited papers together with the discussion occupy the remaining two-thirds of the book. The authors are well known and there is a great deal of useful information on a variety of related topics. The publishers and editors are to be congratulated on the rapid appearance of this handsome volume, nine months after the symposium, a worthy tribute to Lord Wynne-Jones.
