Natural optical activity of CdS crystals in the exciton region of the spectrum
Ivchenko E.L., Permogorov S.A., Sel'kin A.V.
We have investigated experimentally, for the first time ever, the natural optical activity (NOA) of CdS crystals. The reflection spectra have revealed a special type of NOA, which is typical of the crystal classes C3„, C4v, and C6v.
