Description and Table of Contents
Description
This volume provides the basic principles of nuclear magnetic resonance and magnetic relaxation, with the aim of helping students and researchers in various fields of science and technology to obtain a deeper understanding of the subject. It reviews the nature of spin operators and the commutation relationship between them, the behaviour of nuclear magnetism in a static field, and describes the basic theory of the resonance absorption spectrum. The book evaluates Kubo and Tomita's theory which correlates NMR lineshape with the spin Hamiltonian. It also reviews the relationship between magnetic relaxation and molecular motion and deals briefly with recently developed high resolution NMR techniques for studying solid matter. This work will prove to be an indispensable source of information for students and graduate students in chemistry and physics, and for researchers working in the field of NMR.
