Abstract

The nematic phase and the viscous isotropic (VI) phase formed by solutions of CTAB and SHNC are investigated using light scattering and viscosity techniques. It is argued that the turbidity in the nematic phase is due to orientational fluctuations in the director and therefore the intensity scales as Q ⁻². It is shown that with dilution of the nematic phase with water the turbidity disappears with a simultaneous increase of viscosity.
