Intermolecular interactions. By Werner Gans and Jan C. Boeyens. New York: Plenum Publishing Corporation, 1998. Pp. viii + 169. Price US $95.00. ISBN 0-306-45922-1.

This volume `contains most of the invited lectures of the 2nd Structural Chemistry Indaba on Molecular Interactions held at Skukuza, Kruger Park, South Africa, August 3–8, 1997'. The conference addressed the proposition that the structure of a molecule may only be defined, if at all, in the context of its immediate environment. Professor Boeyens contributes an introduction proposing that all interatomic interactions are essentially manifestations of the same phenomena with the distinction between inter- and intra­molecular interactions being made on the basis of reversibility versus irreversibility of bonding.
