摘要

The formula for the intensity of surface second-harmonic generation circular dichroism (SHG-CD) in helical molecular films is presented. The influence of the pitch and radius of helical molecules on the surface SHG-CD intensity is numerically analysed. The existence of a peak in the curves of the surface SHG-CD intensity versus the pitch and radius is predicted. The relation between the pitch and radius for different azimuthal angles is also discussed.
