Abstract
NMR quadrupole splittings and/or chemical shift anisotropies have been studied for several counterions (19F, 133Cs and 7Li) in various liquid crystalline systems. It was observed that these parameters were dependent on concentration of the components in the system and on the phase structure. For the decylammonium fluoride — heavy water system, chemical shift anisotropy changed sign between hexagonal and lamellar liquid crystalline phases and the values of the shift anisotropy in the lamellar phase were two times greater than in the hexagonal phase. The phase diagram following this principle has been determined for the system [1].KeywordsLiquid CrystalSurfactant ConcentrationQuadrupole SplittingHexagonal PhaseInfinite DilutionThese keywords were added by machine and not by the authors.
