Abstract
Addition of chiralic non-mesomorphic molecules to a nematic mesophase produces an optical rotatory power which exceeds the specific rotation of the optically active solutes by a factor of several orders of magnitude. Further, a circular dichroism is induced which causes temperature-dependent selective reflection colours characteristic of cholesteric phases. From this, it may be deduced that chiralic molecules transform nematic into cholesteric phases. The screw-sense of the cholesteric arrangement is determined by the chirality of the optically active solute.
