A solution that rotates plane-polarized light clockwise (+).
The percentage of one enantiomer in excess of another.
A solution that rotates plane-polarized light counter-clockwise (-).
The ability for a solution to rotate plane-polarized light that is passed through it.
The amount by which a given sample rotates plane-polarized light, in degrees. Depends on the concentration, sample path length, and the nature of the sample.
Any substance that exhibits optical activity.
The technique of measuring the optical activity of a compound.
A solution in which both enantiomers of a compound are present in equal amounts.
Property characteristic of a given compound. Conventionally measured at 20 degrees Celsius with the D-line of sodium.
