Organic PhotochemistryIn the decade after this book first appeared in 1974, research involving organic photochemistry was prolific. In this updated and expanded 1986 edition the authors summarise those classes of reaction that best illustrate the types of photochemical behaviour commonly observed for simple organic molecules. The different products obtained from compounds subjected to thermal and photolytic activation are explained with the aid of appropriate diagrams and mechanistic schemes. Where necessary, these are backed up by simple energy level profiles. Thus, theory and empirical data are interwoven to provide a firm basis which is aided by the generous basic references at the end of each chapter. |
