Abstract | In chiral tilted smectic phases transverse molecular dipoles within a smectic layer order polarly as well as quadrupolarly. Electrostatic dipolar and quadrupolar interactions vanish between two smectic layers without positional correlations of molecules and exist only when the positions of molecules in the two layers are correlated. Therefore the interlayer electrostatic interactions are of short range and are expected to act only between nearest and next nearest layers. Dipolar interactions prefer antiferroelectric ordering of the tilt vectors in the layers, while the quadrupolar interactions favour to have the tilt vectors in the two layers in two perpendicular directions. | |
