The zero-field splitting parameters of the lowest triplet state of toluene in a benzene crystal have been measured: D = 0.146, IEI = 0.0463 cm-l. The relative contributions of the three spin levels to the radiative decay in four vibronic bands have been determined. The results indicate that the axes
