X-Ray Diffraction by Incommensurate Liquid Crystals

Part of the NATO ASI Series book series (NSSB, volume 166)

Abstract

The comparison between X-ray patterns of various liquid crystalline phases can solve the problem of the existence of incommensurability in liquid crystals similar to the incommensurability in crystals. Modulation occurs more easily over the liquid order than over the remaining periodic molecular ordering which can be found in smectic and columnar phases. Differences and similarities between the behavior of modulated liquids and crystals are here reviewed.
