— For a model structure the wavelength dependence of action dichroism is computed as a function of the angle(△) between the transition moments at two different wavelengths. With as small an angle as △ α = 20. inversion of action dichroism for parallel vs perpendicularly vibrating radiation is expected for different absorption bands if the sensory pigment molecules are in proper orientations. Thus published data on opposite action dichroism in the blue vs near‐UV range are compatible with flavins as sensory pigments, although the calculations must not be considered as proof for the flavin hypothesis.
