Abstract Using optical second-harmonic generation, we have measured the anisotropic orientation behavior of liquid crystal (LC) molecules in thin films. A high degree of in-plane anisotropy was obtained by depositing the LC films onto rubbed polyimide-covered substrates. The analysis with respect to the relevant second-order susceptibility tensor components is based upon the experimental results obtained in transmission geometry using different angles of incidence for the separation of isotropic and anisotropic contributions.
