dc.description.abstractA rigorous theory of the optical properties of absorbing mixtures of left and right handed cholesteric liquid crystals has been developed. Detailed expressions and illustrative calculations of the dependence of circular dichroism on pitch and sample thickness are pre- sented. Experimental studies have been carried out on a 1.64: 1 (by weight) mixture of cholesteryl myrisate in which was dissolved 1.48% ( by weight ) of linearly dichroic (β-carotene. The variation of circular dichroism with pitch exhibits anomalous behaviour, the sign of the dich- roism being opposite below and above the nematic temperature. The peak value of the circular dichroism (per unit thickness) decreases as the sample thickness increases from 4 to 12.7 μ. These features are in quali- tative agreement with the predictions of the theory.en
