Definitions:

Diastereomers

Stereoisomers that are not mirror images of each other, having two or more stereocenters and differing in the configuration at one or more of these centers.

Enantiomers

Molecules that are mirror images of each other but cannot be superimposed, similar to right and left hands, often displaying different properties in biological systems.

Diastereomer

Isomers in stereochemistry that don't act as mirror counterparts and exhibit unique physical and chemical traits.

Specific Rotation

A property of chiral substances that measures the direction and degree to which they rotate plane-polarized light.
