✦ Synopsis
We have measured the spin-lattice relaxation rates in the phosphorescent triplet state To of naphthalene in durene as a function of the &e&on of the magnetic field-The orientational dependence of the reIaxation is explained by thermal activation to a close Iying local phonon state where the spin axes are rotated with respect to those in TO-l_ Intwkction
