High Resolution NMR: Theory and Chemical Applications, Second Edition covers the significant progress in understanding the NMR phenomena, instrumentation, and applications in chemical and biochemistry. This edition is divided into 14 chapters and begins with the historical developments and theoretical aspects of NMR. Considerable chapters are devoted to the basic principles, chemical shifts, coupling constants, and analysis of complex spectra. Other chapters contain expanded topics on carbon-13, nuclear Overhauser effect, relaxation mechanisms, and the use of superconducting magnets. The remaining chapters examine the concepts of solvent effects, hydrogen bonding, and the use of NMR in quantitative analysis. This book will prove useful to analytical chemists, biochemists, and researchers.
