The polarized Raman spectra of anthracene single crystal are accurately measured by photoelectrical method. All the strong lines are polarized in the cc and bb polarizations, and they should be assigned to the A g representation in the molecular symmetry group of anthracene. The polarization data are not sufficient to decide the symmetry of a Raman line; therefore, the assignments recently reported by Suzuki, Yokoyama anb Ito f and by Ting 2 based on polarizations have to be revised. The correct assignments agree very well with the fluorescance work by Lacey and Lyons, 3 and offer strong evidences supporting our theory proposed recently. 4 This theory is also tested by calculating the polarization of the most intense line at 1401 Kaisers (cm −1 ) . The resut is very good.
