Definitions:

Diastereomers

Stereoisomers that are not mirror images of each other, having two or more stereocenters.

Optical Activity

The property of chiral molecules to rotate plane-polarized light, a phenomenon measured using polarimetry.

Enantiomer

Molecules that are mirror images of each other but cannot be overlaid onto each other, much like left and right hands.

Meso Compound

A type of stereochemical isomer with multiple stereocenters that is superimposable on its mirror image, making it achiral despite containing chiral centers.
