Polarized UV-Visible absorption and rotation-angle second harmonic generation (SHG) techniques were used to investigate the in-plane symmetry in Y-type Langmuir-Blodgett(LB) multilayers of a hemicyanine dye interleaved with inert material arachidic acid. Dipping-induced anisotropy of the molecular orientation with a unique reflection symmetry was enhanced with increasing the dipping speed.
