On the circular dichroism and rotatory dispersion in cholesteric liquid crystals with a pitch gradient

S. Mazkedian , S. Melone , F. Rustichelli

The circular dichroism and rotatory dispersion of a cholesteric liquid crystal with a pitch gradient have been theoretically investigated, by using a simple model, for several values of the gradient and of the cholesteric thickness. All the obtained results have been interpreted by simple physical considerations.
