IR correlation function analysis of benzene ring rotations in liquid crystals
S. Lugomer
Abstract
The IR correlation functions C (t) of liquid crystal diheptyloxyazoxybenzene have been calculated for benzene ring rotations in the smectic, nematic and isotropic phases. It has been found that the benzene ring rotates in random angular jumps of 30° in the smectic phase and of 60° in the nematic and isotropic phases. The rotational correlation times (R. C. T.) are of the order of 10- 12 s and appear to be comparable with R. C. T. of benzene ring rotations in ordinary organic liquids.
