WebThis phenomenon was discovered in 1895 by the French physicist Aimé Cotton (1869–1951). The Cotton effect is called positive if the optical rotation first increases as the wavelength decreases (as first observed by Cotton), and negative if the rotation first decreases. [1] A protein structure such as a beta sheet shows a negative Cotton effect.

"WebLinearly polarized, monochromatic light impinging at 45 degrees to the optical axis can be thought of as the sum of two components, one parallel and one perpendicular to the optical axis of the PEM. The birefringence introduced in the plate will retard one of these components more than the other, that is the PEM acts as a tunable wave plate. " - Circular dichroism wiki
