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

The three spin-lattice relaxation rates for the triplet state of ncridine in zerc-field have been determined in a biphenyl host from 1.7-3.2 K. The mean relaxation rate for the triplet state of phcnanthrene was determined in a biphenyl host from 1.3-13 K Two conclusions of a more general nature emer
It is shown that the spm-spin and spin-lattice relaxation rates in the lowest triplet state of aniline in a p-xylene host crystal are determmed by the presence of a close-lying local phonon state. It is concluded that the motion of the aniline molecule has a highly localised character.
