The optical torque is experimentally studied in Disperse Red dichroic dye doped E7 nematic liquid crystal. Creation of a transitory out-of-plane (3D) anisotropy axis is observed in a geometry were in-plane reorientation is observed in pure nematics. The non-monotone behavior of dye absorption during the excitation and relaxation is con-elated with the 3D reorientation. This shows that the photo-isomerization of the dye via transient excited states (particularly of Cis form) should be the mechanism, which (gives a "Pulse" for the creation of the 3D anisotropy axis.
