Concise, comprehensive coverage of the theory of NMR phenomena primarily from the perspective of proton resonance. These volumes focus upon magnetic nuclei of molecules, how they can be identified with individual spin systems and how to determine the spectral parameters, given the key to structure elucidation, i.e., the use of chemical shifts and coupling constants from the measured spectrum. Also discussed are operation principles and technical problems of traditional (CW) and modern (FT) spectrometers. Specific attention is given tospecial techniques of measurement, such as the measurement and use of various double resonance spectra, temperature-dependent measurements important in the investigation of dynamic phenomena and the measurement of integrated intensities permitting quantitative analysis. Theoretical foundations of Fourier transform spectroscopy, experimental determination of relaxation times, the theory of relaxation, and relaxation mechanisms are discussed and represented schematically. Volume III contains problems in structure determination; solutions to the problems are included as well as over 200 accompanying spectra to permit practical experience with the material. -- AATA
