Orientation of the Absorption and Emission Transition Moments of Methine Dyes

  • Z. Salamon , A. Skibiński and K. Celnik


The emission anisotropics of the fluorescence of the prolate molecules 2[4(N,N-dimethyloamino)-α styrylo]benzothiazol and 2[4(N,N-dimethyloamino)α styrylojbenzoksazol in solvents of different viscosities were measured, yielding information about the rotational motion of the molecules.

The non-linear dependence of 1/r on T/η was confirmed. On the basis of a comparison of experimental and quantum chemical calculations the orientation of the transition moments of the dye molecules is proposed.
