Is it true that chiral compounds rotate plane-polarized light through differential refractive indices for circular polarizations?

The property of optical activity—where chiral media rotate plane-polarized light due to differing refractive indices for left- and right-circularly polarized components (circular birefringence)—is a foundational, textbook principle of physical chemistry and optics requiring no further citation.

Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The claim states the fundamental physical definition of optical activity (circular birefringence), which is universally established in physics and chemistry by definition and direct observation. Step 0 dictates classifying such basic definitions as common knowledge without needing citations.
