Advances in Magnetic Resonance

Advances in Magnetic Resonance, Volume 4 deals with the relaxation, irradiation, and other dynamical effects that is specific to systems having resolved structure in their magnetic resonance spectra. This book discusses the anisotropic rotation of molecules in liquids by NMR quadrupolar relaxation; rotational diffusion constants; alternating linewidth effect; and theoretical formulations of the problem. The line shapes in high-resolution NMR; matrix representations of the equations of motion; matrix representations of the equations of motion; and intramolecular hydrogen bonds are also deliberated. This text likewise covers the nuclear spin relaxation by double resonance and methods of solution of the density matrix equations. This publication is valuable to physics and chemistry students, including those interested in magnetic resonance.
