Pretransitional Behavior in the Isotropic Phase of Homologous Compounds Showing Nematic and SmecticC type order. We have measured the intensity and spectrum of scattered light in the isotropic phase of dialkoxyazoxybenzenes with terminal octyl (C.H.), decyl (C.H.), and undecyl (C.H.) groups.. All three compounds have a smectic C phase. The octyl and decyl compounds also have nematic phases over a

Stability of Molecular Order in the Smectic a Phase of a Liquid Crystal,atic-smectic A phase transition in the presence of a magnetic field. The direction and degree of order were determined using pulsed nuclear magnetic resonance techniques. The order was observed to change with time following a rotation of the magnetic field. The degree and stability of order produced

Rotational Diffusion in the Nematic Phase: Part I, on the time dependent angular distribution function which is obtained by solving a Vlasov-type equation including the effect of molecular collisions, A perturbation technique of the Bhatnager-Gross-Krook (BGK) model is used for the collision term and for the linearization of the equation.

Kinetics of Field Alignment and Elastic Relaxation in Twisted Nematic Liquid Crystals,holesteric liquid crystals if the molecular alignment is parallel to the walls but differs in direction at the two surfaces. Such an arrangement is known as a twisted nematic. A 90° twist leads to a 90° rotation of linearly polarized light travelling normally to the orienting surfaces provided the d
