Liquid crystals and ordered fluids
TL;DR: In this paper, the authors present a NMR study of the transition of a mixture of two Isomeric Cyano-Ester homologous series, showing that the phase transition of one of the two isomeric versions of this series is a transition of the other.

Rotatory power and other optical properties of certain liquid crystals
TL;DR: In this paper, it is shown how these properties can be explained by the assumption that the molecules are arranged in a special way, so that the electrical axes rotate screw-like.

Guest-host Interactions in Nematic Liquid Crystals. A New Electro-optic Effect
G. H. Heilmeier,L. A. Zanoni +1 more
TL;DR: In this paper, the ability of a nematic liquid crystal to cooperatively align in an electric field is used to orient "guest" dichroic dye molecules (molecules whose absorption spectrum is a function of the molecular orientation with respect to the polarization of the incident light).
Journal ArticleDOI
Dynamic scattering: A new electrooptic effect in certain classes of nematic liquid crystals
TL;DR: In this article, a new electrooptic effect in certain classes of nematic liquid crystals is presented, termed "dynamic scattering" because scattering centers are produced in the transparent, anisotropic medium due to the disruptive effects of ions in transit.
Journal ArticleDOI
Domains in Liquid Crystals
TL;DR: In this article, a regular domain pattern has been observed to form in nematic liquid crystals when an electric field is applied to the liquid, which is visible in unpolarized light by either transmission or reflection.
