Study on Surface Second Harmonic Generation-Circular Dichroismof Chiral Molecular Films
The formula of the intensity on the reflected direction of second hormonic generation circular dichroism (SHG CD) is presented. The relationship between the intensity of surface SHG CD and pitch, radius and azimuthal angle of molecules in helix molecular films are analyzed, and the numerical simulation results are given. It shows that in the value range of pitch or radius, there exists the maximal intensity of SHG CD respectively. And the relation between pitch and radius is different to the varying azimuthal angle of molecules.
