"Theory of Magnetic Resonance" by Charles P. Poole Jr. & Horacio A. Farach is a comprehensive textbook on the subject of magnetic resonance theory. This second edition, published in 1987, covers important aspects of the theory that are relevant to research workers in the fields of chemistry and physics. The book presents mathematical background and a basic prototype two-spin 1/2-1/2 Hamiltonian treatment, and then discusses specialized extensions such as ENDOR, ELDOR, polarization, spin labels, saturation transfer, and NMR imaging. Illustrated and weighing 24.1 oz, this 384-page hardcover book is a valuable resource for scholars and professionals interested in the science of magnetic resonance.
