Recent years have seen a steady increase in the chemical uses and in the analytical importance of high-resolution nuclear magnetic resonance (NMR) spectroscopy. In this expanding field, new experimental procedures and fresh developments follow each other in quick succession. Pulsed Fourier transform (FT) facilities and superconducting magnet systems, which a decade ago were regarded as exotic technical aids only to be considered in exceptional circumstances, are today in routine use in many analytical laboratories. There was thus a pressing need for revision of the 1973 Edition of this German text-book, written by an experienced spectroscopist at Siegen University. An excellent English translation ("N.M.R. Spectroscopy," Wiley , Chichester) of an up-dated and extended version of the original German text appeared in 1980.The first six chapters of the new Edition are virtually the same as those of the 1973 Edition, and provide an informative introduction to the physical basis of continuous-wave proton NMR spectroscopy and to its applications in organic chemistry; a series of instructional exercises (with answers), selected to help tyros, supplement the text. The three following chapters contain short accounts of, inter a h , relaxation effects, pulsed F T methods, dynamic NMR and lanthanide shift reagent studies, superconducting magnets, double resonance experiments, the nuclear Overhauser effect and NMR imaging. Tables of proton chemical shift and of
