Description
Understanding NMR Spectroscopy
James Keeler Department of Chemistry, University of Cambridge, UK
This text is aimed at people who have some familiarity with high-resolution NMR, and who now wish to deepen their understanding of how NMR experiments actually work The book concentrates on those experiments which are commonly used in structural studies of small- to medium-sized molecules. Although the special experiments used in biomolecular NMR are not considered explicitly, the key concepts and ideas introduced in this book are very relevant to understanding such experiments.
The book starts off at a gentle pace, working through some more-or-less familiar ideas, and then elaborating these as the discussion progresses. Sufficient quantum mechanics is introduced to enable a proper analysis of the pulse sequences, but the approach taken is informal. All of the calculations are gone through step-by-step, with commentary on each stage so that you can see exactly what is going on.
This is neither a how to book, nor a book about the theory of NMR. Rather, the aim of the text is to give the reader a set of tools with which to analyse and think about modern NMR experiments.
Each chapter ends with exercises which are designed to assist in the understanding of the ideas presented. A solutions manual for these exercises is available on-line via the SpectroscopyNow website: http://www.spectroscopynow.com/nmr
