M. Rajteri et al., OPTICAL-ACTIVITY OF SMALL PITCH CHIRAL SMECTIC-C LIQUID-CRYSTALS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 302, 1997, pp. 139-143
Recently it has been shown that chiral smectics C liquid crystals with
pitch shorter than the light wavelength are optically active with max
imum rotatory power for light propagating orthogonally to the helix ax
is. We report the first experimental evidence of this fact.
