✦ Synopsis


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 emerge: (1) the rchxation amongst the spin Components of a given triplet state in zero-field may be markedly-ulisotiopic; (2) the time SC& on which rclzarion occtss may vary by several orders of magnitude for different molecules.

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.
