Abstract
We determine the orientation of the optical transition moments of the fluorescent probe trimethylammonio-diphenylhexatriene (TMA-DPH). This is accomplished using angle-resolved steady-state fluorescence depolar ization experiments on TMA-DPH embedded and immobilized in a stretched anhydrous poly(vinylalcohol) film matrix. The absorption moment was f ound to lie parallel to the long axis of the chromophore. The emission moment makes an angle of 18 +/- 2 degrees with this axis.
