Advances in Magnetic Resonance, Volume 12, presents a variety of contributions to the theory and practice of magnetic resonance. The book contains six chapters and begins with a discussion of diffusion and self-diffusion measurements by nuclear magnetic resonance. This is followed by separate chapters on spin-lattice relaxation time in hydrogen isotope mixtures; the principles of optical detection of nuclear spin alignment and nuclear quadropole resonance; and the spin-1 behavior, including the relaxation of the quasi-invariants of the motion of a system of pairs of dipolar coupled spin-1/2 nuclei. Subsequent chapters deal with the development and application of crafted pulse shapes in nuclear magnetic resonance, magnetic resonance imaging, and optical coherent transient (laser) spectroscopies; and the application of pulsed proton nuclear magnetic resonance "broad line" spectroscopy as a thermal analysis technique and its use to study thermal transformations in hydrogen-containing solids, in particular coals and related organic materials.
