Singlet and triplet exciton energy migration in the charge-transfer crystal of pyromellitie dianhydride-phenanthrene, undoped and doped with anthracene (10-4-10-2 M/M), have been studied in the 5-300 K temperature range. At low temperatures singlet and triplet excitons are self-trapped. They become
