Very weak fluorescence in the ultaviolet (210-380 nm) is observed when an anthracene crystal is excited at 397 nm. They are assigned as fluorescence from S2 and S1 states in the crystal. These higher excited states are populated by fusion of two S, excitons.

Photobleaching of disubstituted (methyl and phenyl) anthracenes in thin polymer films has been observed under inert atmosphere with both direct and triplet sensitized excitation, exhibiting both wavelength and intensity dependence of quantum yields (which are in the range z 10-2-10-'). The data arc
