Abstract

At a certain temperature T_n (nematic temperature) a mixture of two cholesteric components which separately form helices of opposite senses behaves like a nematic. An inversion of the helical structure occurs when passing T_n, from a right-handed to a left-handed structure or vice versa. In the temperature-pressure space such compensated mixtures therefore will exhibit an inversion line which - on the basis of optical rotatory power measurements under high pressure - is presented for the first time.
