Abstract
A new mechanism is proposed for spin-lattice relaxation (SPL) in the phosphorescent triplet state of a molecule that has no inversion point. The mechanism is based on the fact that the internal spin-orbital interaction in a molecule allows the transition between spin sublevels of the triplet induced by the variable crystal field of the lattice.
