Chiral optical absorption bands in []Cd1−x Mnx Ga2S4 semiconducting compound

Power dependence on the rotational strength in a quartz crystal

“…Recent investigation in defect ternary compounds confirmed that there are some semiconducting compounds [10][11][12] which also have optical activity even though they have established symmetry elements. There are also some other materials like nano-particles and organic compounds which show optical activity.…”

“…The displacement of the charge distribution from the equilibrium configuration creates an electric dipole moment [13] near the vacancy. In this situation it was found that [11,12] the component of the electric dipole moment is parallel to the magnetic dipole moment [12], which is a required condition for optical activity. This charge displacement is proportional to the magnitude of the electric vector of the incident radiation for low intensity of radiation and for higher intensities it will tend to saturate.…”
