optical rotation the quality of certain optically active substances whereby the plane of polarized light is changed, so that it is rotated in an arc the length of which is characteristic of the substance.

analysis chirality inversion polarimeter rotation stereochemistry			With our many in house quality assurance tools including mass spectrometry, gas chromatography, refractive index, specific gravity, optical rotation, flash points, head space analysis and a variety of wet analysis capabilities, we make every attempt to identify anomalies that would affect our customers' products. Berje Inc by Household & Personal Products Industry One PV observable is the effect of the weak interaction on neutrons passing through matter, which is analogous to the optical rotation of polarized photons traveling through a "handed" medium [5].
