• Sommario/riassunto: This book is for those familiar with solution-state NMR who are encountering solid-state NMR for the first time. It presents the current understanding and applications of solid-state NMR with a rigorous but readable approach, making it easy for someone who merely wishes to gain an overall impression of the subject without details. This dual requirement is met through careful construction of the material within each chapter. The book is divided into two parts: ""Fundamentals"" and ""Further Applications."" The section on Fundamentals contains relatively long chapters that deal with the bas
