WebAug 12, 2024 · Among these properties are circular light polarization and optical rotation for evaluating the performance of chiral targets. It is well-known that the optical fields rotate at a constant rate in a plane during circular light polarization when the waves travel ( Desmarais, 1997; Singh, 2015 ).

Optical activity occurs due to molecules dissolved in a fluid or due to the fluid itself only if the molecules are one of two (or more) stereoisomers; this is known as an enantiomer. The structure of such a molecule is such that it is not identical to its mirror image (which would be that of a different stereoisomer, or the "opposite enantiomer").
