Abstract
We have employed the nuclear magnetic resonance technique to study the little understood ’’blue phase’’ of the cholesteric liquid crystals—cholesteryl benzoate, cholesteryl methyl carbonate, cholesteryl ethyl carbonate, and cholesteryl laurate. The NMR spectra in the ordinary cholesteric phase has both structure and width; these features are reduced in the blue phase, where they resemble isotropic phase spectra. The presence of a NMR line wider than in the isotropic state, however, indicates the presence of long range orientational order and provides data which throw some light on the possible structure of the blue phase.
