Optical rotatory dispersion — is the variation in the optical rotation of a substance with a change in the wavelength of light. Optical rotatory dispersion can be used to find the absolute configuration of metal complexes. For example, when plane polarized white light from an … Wikipedia
rotatory dispersion — noun : the production of colors that results from passing white light through an optically active substance (as quartz) that causes the amount of optical rotation to vary with the wavelength … Useful english dictionary
Optical rotation — (optical activity) is the turning of the plane of linearly polarized light about the direction of motion as the light travels through certain materials. It occurs in solutions of chiral molecules such as sucrose (sugar), solids with rotated… … Wikipedia

Aimé Cotton — Aimé Auguste Cotton (9 October 1869 16 April 1951) was a French physicist known for his studies of the interaction of light with chiral molecules. In the absorption bands of these molecules, he discovered large values of optical rotatory… … Wikipedia
Magnetic circular dichroism — (MCD) is the differential absorption of left and right circularly polarized (LCP and RCP) light, induced in a sample by a strong magnetic field oriented parallel to the direction of light propagation. MCD measurements can detect transitions which … Wikipedia
Circular dichroism — (CD) refers to the differential absorption of left and right circularly polarized light.[1][2] This phenomenon was discovered by Jean Baptiste Biot, Augustin Fresnel, and Aimé Cotton in the first half of the 19th century.[3] It is exhibited in… … Wikipedia
