Spin-lattice coupling constants of a Mn++ ion in a cubic environment are calculated on the overlap and covalent model. It is found that only the overlap model can account for the signs of the constants in the case of Mn++ in MgO, that is, the Mn-O bond is mainly of ionic character. The spin-lattice relaxation time is expressed in terms of the coupling constants for the one phonon process. Its magnitude is a reasonable one, when the observed values of the coupling constants are used.
