Abstract

We have determined the orientational distribution functions (OBFs) at both air and substrate isotropic interfaces of a chiral chitosan bio-polymer film by the measurements of surface second-harmonic generation (SHG). It was shown that the simultaneous SHG analysis of both interfaces, based on the macroscopic and microscopic relations, provides all the informations on the nonlinear optical (NLO) activity.
