Paper Abstract

We show that collective Cotton-Mouton (C-M) effect can be used to determine the anisotropic orientational arrangement of molecules within scattering centers such as colloid and suspension particles. The technique applied to liquid-crystal suspensions indicates that both smectic-nematic and nematic-isotropic transitions can be easily determined within mesogenic droplets. The measurements were performed on mesomorphic 4-cyano-4'-(n-octyl) biphenyl having both smectic A and nematic phases. Using the generalized nth order Langevin's functions L(subscript n%/, the statistical model is presented for the collective C-M effect in the monodisperse suspensions of smectics and nematics.
