We have observed a temperature dependence of the direction of the principal axes of the zero-field splitting for the triplet state of naphthalene in durene. The effect is caused by thermal excitation to a nearby local phonon state, where the spin itYes are rotated with respect to those in the lowest

Spin-lattice relaxation rates in the Tt triplet state of 9,lOanthraquinone dissolved in n-heptane and isooctane are measured in the temperature region 1.9 to 30 K using an excitation of phosphorescence by short flashes. The relaxation rates are determined from the tri-evponential decay curves measur
