Abstract

Abstract Proton N.M.R. is used to investigate the inclusion of the phenylsulphonate and the benzoate ion as counterions in samples of amphiphilic nematic liquid crystals. When these aromatic counterions are substituted in sufficient amounts the sign of the diamagnetic anisotropy is reversed. The orientation parameters are also shown to be dependent upon the micelle shape, as well as the sign of the diamagnetic anisotropy.
