“…In order to explain these results it is necessary to introduce lattice temperature in the theory of cross relaxation. Such an attempt (Sikri and Narchal 1978) has been made with regard to Grant's theory of two-spin CR for particles of spin 4. This temperaturedependent theory has been applied to Mims' (Mims and McGee 1960) experiment on ruby and produces better agreement with it in the negative frequency region, whereas Grant's theory (Grant 1964a, b, c, d, e) agrees with experiment in the positive frequency region.…”

A temperature-dependent statistical theory of two-and three-spin cross relaxation processes is developed for S = 1 paramagnetic ions. It takes account of fluctuations of magnetic quantum numbers of the ions due to spin-spin and spin-lattice interactions in terms of the ensemble theory of statistical mechanics. Explicit two-and three-spin resonant cross relaxation rates are computed for Ni2+ ions in the diamagnetic host lattice of dioxane and compared with experimental results. Reasonably good agreement is obtained with experiment, both with regard to temperature dependence and the actual magnitudes of two-and three-spin cross relaxation rates.

“…For explaining the two-spin results it is necessary to introduce some changes in the two-spin theory for spin 3 particles discussed by Sikri and Narchal (1978), in order that it becomes applicable to the experiment under consideration. This is done in $2.…”
