Nuclear Spin Relaxation in Diamagnetic Fluids: Part 1. General Aspects and Inorganic Applications

Abstract

Publisher Summary Studies of nuclear spin relaxation phenomena are a rich source of dynamic and structural information about the species ranging from simple fluids to complex macromolecular systems. This chapter reviews the applications of nuclear magnetic relaxation measurements. The theory of nuclear spin relaxation is also reviewed in the chapter. Dipole-dipole (DD) relaxation in spin systems of more than two spins and in systems with indirect spin-spin coupling (and possibly chemical equivalence and double resonance irradiation) is an active field of research. The experimental and methodological aspects of relaxation studies and relaxation measurements in gases are discussed in the chapter. Nuclear spin relaxation rates due to the intermolecular dipole-dipole interaction modulated by relative translational motion were obtained. Spin-lattice relaxation measurements are usually performed, using simple sequences of non-selective (hard) pulses, with or without double resonance irradiation. The inorganic system is any system not containing carbon atoms or any low-molecular weight system containing metal atoms. Thus, the chapter discusses the relaxation measurements in inorganic liquid systems.
