liquid crystalsatomic modelscinnamic acidThe optical properties, orientational ordering, and anisotropy of a local field in a nematic liquid crystal of cyanophenyl heptylcinnamate have been investigated experimentally. The functional dependence of the anisotropy of the molecular polarizability on the ...

We shall try here to present two different models that are used in this field, and which are based on two rather opposite pictures of a liquid, the solid-like picture and the gas-like picture. Emphasis will be particularly put on the former one, giving reasons why we believe it is (...
For water molecules in liquid, F3 = 0.09; for water molecules in hydrate, F3 = 0.01. Free energy calculation The free energy of the three-body interactions for methane was calculated by the extended-system adaptive biasing forces (eABF)54, which is a variant of the adaptive ...

16 During evaporation, molecules escape rapidly from the surface of a liquid.What happens to the average energy of the molecules of the remaining liquid and what happen to the temperature of the remaining liquid?A average energy of temperature of remaining molecules remaining liquid A decreases decr...
The FLC composite is made up of a ferroelectric liquid crystal, SCE 13, doped with 5% of 4-dimethylamino-4-nitro stilbenes (DANS) in weight. It is found that the SHG intensity from the doped DANS molecules is greatly enhanced by the polar order present in the FLC environment. Moreover, ...
