Abstract

LOW-ANGLE X-ray diffraction has shown the existence of a viscous isotropic (cubic) mesomorphic phase in a number of surface-active agent plus water systems1–4 at concentrations between those required for the formation of neat (lamellar) and middle (hexagonal) mesomorphic phases. Initially, a face-centred cubic (fcc) lattice was proposed1 for this viscous isotropic phase and several possible model structures have been advanced5. Luzzati et al. have recently proposed6, however, that all reported cubic mesomorphic phases are based, not on an fcc lattice, but on the same body-centred cubic (bcc) lattice, space group Ia3d in the International Tables7.
