Definitions:

Enantiomers

Mirror-image forms of a molecule that cannot be superimposed on each other, often having different properties in a chiral environment.

Polarized Light

Light waves where vibrations happen on just one plane.

Specific Rotation

A measure of the degree to which a compound can rotate plane-polarized light, specific to its concentration and the length of the light path through the sample.

(S)-glyceraldehyde

The S-configuration enantiomer of glyceraldehyde, which serves as a standard for determining the absolute configuration of chiral molecules.
