The present volume was begun by the late Dr. H.-O. Kalinowski, Justus-Liebig-Universitat, Gieen, 13 Germany who could not continue the work on it. His books about the theory and applications of C NMR are well known and helpful to many chemists. The authors and the editors dedicate the volume to the memory of Dr. H.-O. Kalinowski. Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, oriented by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum. The spectral lines of the nuclei are highly influenced...
