The optical anisotropy of organic molecular films induced by molecular reorientation was investi-gated by using the perturbation method.We presented theoretical formulae about the dependence of second harmonic generation (SHG) intensity on the polarization of fundamental beam.SHG beam and the dipping direc tion.The experimental studies and discussion were given under some special conditions.The expermental results agreed well with the theoretical calculation.
