Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and versatile techniques now available for the study of molecular structure and reaction mechanisms. This classic account of modern NMR spctroscopy was heralded on its publication in 1987 as `the lasting text of its age' Nature. Now available in paperback, it provides a thoroughly comprehensive review of modern NMR techniques and the underlying principles. The material is presented in an intuitive manner within a rigourous mathematical framework, and is extensively illustrated throughout. It is, without question, an essential purchase for the self-respecting NMR spectroscopist.
