R.N.IBBETT This book provides a source of information on all major aspects of NMR spectroscopy of synthetic polymers. It represents a deliberate attempt to pull together the numerous strands of the subject in a single comprehensive volume, designed to be readable at every scientific level. It is intended that the book will be of use to the vast majority of polymer scientists and NMR spec­ troscopists alike. Readers new to NMR will find extensive information within the book on the available techniques, allowing full exploration of the many polymer science applications. Readers already established within a branch of NMR will find the book an excellent guide to the practical study of polymers and the inter­ pretation of experimental data. Readers who have specialised in polymer NMR will find the book a valuable dictionary of proven methodologies, as well as a guide to the very latest developments in the subject. Workers from all of the main branches of polymer NMR have been invited to contribute. Each chapter therefore contains information relating to a parti­ cular investigative topic, indentified mainly on the basis of technique. The book is loosely divided between solution and solid-state domains, although the numerous interconnections confirm that these two domains are parts of the same continuum. Basic principles are explained within each chapter, combined with discussions of experimental theory and applications. Examples of polymer investigations are covered generously and in many chapters there are discussions of the most recent theoretical and experimental developments.
