In pursuit of the objective of the series which is to present considered reviews of areas concerned with quantitative study of organic compounds and their behaviourNphysical organic chemistry in its broadest senseNina manner accessible to a general readership, this twenty-ninth volume contains five contributions on a diversity of topics. Two of these reflect the increasing importance of physical organic studies in providing fundamental knowledge relevant to the development of new materials with novel physical properties. The others represent more traditional areas of physical organic interest, where recent research has thrown new light. - Electron storage and transfer in organic redox systems with multiple electrophores - Chirality and molecular recognition in monolayers at the air/water interface - Transition state theory revisited - Neighboring group participation by carbonyl groups in ester hydrolysis - Electrophilic bromination of carbonDcarbon double bonds: structure solvent and mechanism
