Definitions:

Specific Rotation

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

Enantiomeric Excess

A measurement of the purity of an enantiomer in a mixture, defined as the difference in percentage between the two enantiomers.

Diastereomers

Stereoisomers which aren't each other's mirror reflections and possess distinct physical characteristics.

Geometric Isomers

Molecules with the same molecular formula and sequence of bonded atoms (constitution), but differing in the three-dimensional orientations of their atoms in space.
