Optical Rotatory Power

In a binary system of a nematic and a cholesteric liquid crystal an inversion of the helix - sense has been observed at a definite composition xn by measurements of circular dichroism and optical rotatory power. The inversion is accompanied by a decrease of the helical twisting power approaching zero at xn .
