N2 - For the determination of the angle β between the absorption and emission transition moments it seems appropriate to investigate the emission anisotropy as a function of the absorption dichroic ratio, Rd, rather than of the stretch ratio, Rs, of a polymer film. The angles β thus determined for linear molecules of 1, 8-diphenyloctatetraene (DPO), 1, 6-diphenylhexatriene (DPH), 1, 4-diphenyl-butadiene (DPB), 4-dimethylamino-4′-nitrostilbene (DNS), and p-terphenyl (TP) are considerably smaller and closer to the zero value. Slight deviations of the angles obtained from β = 0° result from the effect of limited rotational motions of the luminescent molecules in the polymer.
