Circular birefringence
WebThe measurement of linear birefringence of crystalline materials is described, together with some examples, showing how it is linked to crystal structures, particularly through the study of phase transitions. Circular birefringence (more commonly known as optical activity) has now also been related to structures of inorganic materials. WebCircular polarization: the electric field of the light consists of two linear components that are perpendicular to each other, equal in amplitude, but have a phase difference of π/2. ... If the birefringence of the specimen is known, it can then be used to determine the specimen thickness. If the specimen thickness is known, it can be used to ...

WebCircular birefringence. Circular dicliroism has been a useful servant to tire biophysical chemist since it allows tire non-invasive detennination of secondary stmcture (a-helices and P-sheets) in dissolved biopolymers.
