摘要：

From selective reflection (SR) measurements as a function of temperature it has been shown that cholesteryl myristate exhibits two “blue phases” (BP) between the isotropic and the cholesteric state. The SR of the two BP shows the same angular dependence as found in the cor-responding cholesteric state. From our results a model of the BP is proposed with the molecular axes inclined to the helix axis by a critical angle of 54.74° explaining the absence of birefringence as well as the cholesteric-like optical properties. © 1979, Walter de Gruyter.
