WebThe "optical purity" is a comparison of the optical rotation of a pure sample of unknown stereochemistry versus the optical rotation of a sample of pure enantiomer. It is expressed as a percentage. If the sample only rotates plane-polarized light half as much as expected, the optical purity is 50%. Optical purity also corresponds to ...

WebThe optical rotation is measured on a layer of suitable thickness at the wavelength specified in the monograph. If the sodium D line is specified, the sodium light of wavelength 589.3 nm (a mean value for a doublet at 589.0 nm and 589.6 nm) should be used. The wavelength of the mercury green line at 546.1 nm is also frequently used.
