Solid-State NMR Spectroscopy 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.

Solid-State NMR Spectroscopy is divided into two parts: "Fundamentals" and "Further Applications."

The section on Fundamentals contains relatively long chapters that deal with the basic theory and practice of solid-state NMR. The essential differences and extra scope of solid-state NMR over solution-state is dealt with in an introductory chapter.

The basic principles upon which the techniques in the chapter rely are explained in a separate section. Each of these chapters exemplifies the principles and techniques with the applications most commonly found in current practice.

The "Further Applications" section contains a series of shorter chapters which describe the NMR techniques used in other, more specific areas.
