Quadrupole Splittings in Deuterium NMR-Spectra of the Hexagonal Phase in the System Sodium Octanoate-d₁₅-Water- Carbontetrachloride

Abstract

Abstract The hexagonal phase of the system C7D15COONa-H2O-CCI4 has been studied by deuterium magnetic resonance. Order parameters for the different CD2-groups have been determined from the observed deuterium splittings in powder spectra. The order parameters range from 0.02 to 0.13. The order parameters decrease when CCI4 is solubilized, implying an increased motional freedom of the alkyl chain. For some samples a central, unsplit peak is observed originating from isotropic metastable aggregates.
