XXIIIrd International Congress of Pure and Applied Chemistry, Volume 4 contains papers presented at the XXIIIrd International Congress of Pure and Applied Chemistry held in Boston, USA on July 26-30, 1971. This book is organized into two main topics—short-lived intermediates, free radicals and homolytic mechanisms, and ion pair processes. This publication specifically discusses the chemically induced dynamic nuclear polarization, formation of radical anions by the attack of radicals upon anions, and high temperature organic reactions by flash vacuum pyrolysis. The structure-reactivity relationships in the chemistry of aliphatic free radicals, medium effects on radical-radical reactions, and oxidation of alkyl radicals by metal complexes are also described. This text likewise considers the end group association and complexation in anionic polymerization and reversal of singlet and triplet states in aromatic dianions with trigonal symmetry. This compilation is useful to chemists and specialists researching on pure and applied chemistry.

First multi-year cumulation covers six years: 1965-70.

Includes entries for maps and atlases.

25th International Congress of Pure and Applied Chemistry presents a compilation of papers covering a wide range of topics on applied and pure chemistry. This book discusses the challenges in the field of aromatic photosubstitution. Organized into six chapters, this book begins with an overview of the diverse reactions of aromatic molecules. This text then examines the pattern of specific RNA found in the human tumors, which showed a notable concordance with the predictions deducible from the animal system. Other chapters consider the methods of estimation of chemical fuels and describe the greenhouse effect arising from the burning of coal. This book presents as well an assessment of some features of the impact of quantum mechanics on chemistry. The final chapter deals with molecular beam and spectroscopic methods that allow a detailed investigation of several dynamical properties of single reactive collisions. This book is a valuable resource for chemists, theoreticians, research workers, and scientists.
