This book brings together the three branches of magnetic resonance spectroscopy namely, electron spin resonance (ESR), nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) and presents a coherent and progressive coverage of the subject in a simple and lucid style. Each part covers the physical basis of a related spectroscopic method and its chemical applications. The emphasis is on obtaining and interpreting some types of spectra often met in the laboratory that can be applied in solving problems related to structure and behaviour of organic and inorganic molecules. Each part concludes with references to advanced literature and exercises that test the readers' understanding. This text may be used for self study. The text will benefit post graduate students at M.Sc., M. Phil., and research in Chemistry, Physics, Biology and Pharmacology. The key features: use of Huckel and crystal field theory as tools in the interpretation of spectra; extended coverage of 2D NMR spectra; NMR of nuclei such as 13C, 19F and 31P; non-mathematical description of the experiments; develops the foundation in a clear step-by-step manner; and, end of chapter exercises.
