The polarized emission spectra of anthracene, dibenzothiophene, and xanthone have been studied in stretched polyethylene films at 77 and 4.2 K. Applicability and advantage of this method are examined by virtue of conventional polarization technique and modulation technique. The latter leads us to finding of an important role of a nontotally symmetric vibration, the b<SUB>3g</SUB> ring vibration at 1655 cm<SUP>−1</SUP>, in the fluorescence spectrum of anthracene. An assignment for several prominent vibrational bands in the phosphorescence spectrum of dibenzothiophene is proposed from detailed analysis of the modulation polarization spectrum at 77 K. The phosphorescence properties of xanthone are also investigated.
