Description

This is the second edition of a very successful book which provides the conceptual and experimental basis for the interpretation of 13 C NMR spectra. Considerable emphasis has been placed on the various experimental methods and on the interpretation of spectral details which enable individual resonance lines to be associated with the various carbons in the molecule. The book benefits from the thorough teaching experience the authors have acquired in the large number of 13 C NMR workshops and seminars they have conducted at universities throughout Europe. With the advent of pulsed high-resolution NMR techniques some years ago, 13 C NMR has become one of the most powerful techniques for the organic chemist to tackle structural, stereochemical and conformational problems. Beyond these straightforward applications, 13 C NMR has proven its virtues in such domains as the characterization of synthetic and biological macromolecules, elucidation of reaction mechanisms and for the study of chemical and conformational equilibria. The easy access to spin lattice relaxation measurements further widens the scope of 13 C spectroscopy by providing a further means to study structure and conformation. Here is a guide to the thorough interpretation of your 13 C NMR data.
