Summary:In inorganic crystals, the origin for optical activity is associated with bended bonds created by vacancies. The bended pattern of charge distribution creates a situation where electric and magnetic dipole moments have parallel components and hence, their contribution is more significant than the one derived from atomic polarizability. Numerical calculations have been carried out for a quartz crystal and the results are in agreement with experimental data.
