Nuclear magnetic relaxation studies in solids

Spin-lattice relaxation times in the laboratory and in the rotating frame are reported for trimethyloxosulfonium fluoride, chloride, bromide and iodide as well as for dimethylosulphone and dimethylsulphoxide over a wide temperature range. A model that makes it possible to analyze the experimental data on the basis of four independent reorientations around three threefold axis and around center of gravity is developed. (author)
