The kinetic parameters of the photo-excited triplet state of pentacene in p-terphenyl crystals have been calculated from the electron spin echo (ESE) decay curves in the temperature range of 5-300 K. The results suggest the calculated decay parameters depend strongly on guest deuteration, especially

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.
