N2 - The spin polarization and emissive character of the magnetic resonance spectrum of mobile triplet excitons in tetracene single crystals observed by Yarmus, Rosenthal, and Chopp are interpreted in terms of selective population of the Zeeman sublevels by singlet exciton fission. In addition, the selective population of the triplet sublevel by direct singlet-triplet absorption is calculated. The differences to be expected in the EPR spectrum for these two methods of exciton generation are discussed.
