Abstract
The review presents the main results of the studies of Prof. S. P. Gabuda, which were devoted to the NMR investigation of the mobility of atoms and molecules. The basic principles of his model for averaging local magnetic fields under the conditions of atomic and molecular mobility are outlined. This model provides a relationship between the parameters of these fields with the structural features of the mobility of atoms and molecules and intermolecular interactions. Ionic and molecular crystals, zeolites, molecular sieves, hydrated proteins, and so on are considered. Phase transitions in guest subsystems, effects of dynamic disordering and correlated electron motion on the mobility of atoms and molecules and their location are discussed.
