摘要
EPR studies of the lowest triplet state of anthracene in a phenazine host crystal reveal a non-Boltzmann distribution over the triplet spin levels at approximate to 1.5 degrees K. Measurements of the lifetimes for each of the triplet spin states provide information about both intramolecular decay processes and intermolecular triplet energy transfer mechanisms in the mixed crystal system.
