Optical Activity of Tartaric Acid Stereoisomers

Optical Activity of Tartaric Acid Stereoisomers

This is an automated demonstration enabling the user to measure the optical rotatory dispersion of a mixture of optical isomers

Optical activity of compounds in solution can be measured with a polarimeter, shown schematically in the upper part of the graphic. The angle of rotation of plane polarized light, conventionally the sodium D-line at 589 nm, is determined using two polarizers. (In the...
