This text discusses the high-resolution NMR of liquid samples and concentrates exclusively on spin-half nuclei (mainly 1H and 13C). It is aimed at people who are familiar with the use of routine NMR for structure determination and who wish to deepen their understanding of just exactly how NMR experiments work. It demonstrates that in NMR it is possible, quite literally on the back of an envelope, to make exact predictions of the outcome of quite sophisticated experiments. The experiments chosen are likely to be encountered in the routine NMR of small to medium-sized molecules, but are also applicable to the study of large biomolecules, such as proteins and nucleic acids.
This text is aimed at people who have some familiarity with high-resolution NMR and who wish to deepen their understanding of how NMR experiments actually 'work'. This revised and updated edition takes the same approach as the highly-acclaimed first edition. The text concentrates on the description of commonly-used experiments and explains in detail the theory behind how such experiments work. The quantum mechanical tools needed to analyse pulse sequences are introduced set by step, but the approach is relatively informal with the emphasis on obtaining a good understanding of how the experiments actually work. The use of two-colour printing and a new larger format improves the readability of the text. In addition, a number of new topics have been introduced:
How product operators can be extended to describe experiments in AX2 and AX3 spin systems, thus making it possible to discuss the important APT, INEPT and DEPT experiments often used in carbon-13 NMR.
Spin system analysis i.e. how shifts and couplings can be extracted from strongly-coupled (second-order) spectra.
How the presence of chemically equivalent spins leads to spectral features which are somewhat unusual and possibly misleading, even at high magnetic fields.
A discussion of chemical exchange effects has been introduced in order to help with the explanation of transverse relaxation.
The double-quantum spectroscopy of a three-spin system is now considered in more detail.
