circular birefringence

https://doi.org/10.1351/goldbook.08231
Difference between the refractive indices of an optically active medium for left, nL, and right, nR, circularly polarized radiation (nL−nR).
Notes:
  1. "Circular birefringence" is also used to describe the phenomenon of having different refractive indices for left and right circularly polarized radiation.
  2. Like the refractive indices (nL, nR), circular birefringence changes with wavenumber.
