Abstract

It is known that a mechanism exhists for producing molecular alignment in liquid crystals which is associated with the ionic conduction anisotropy and hydrodynamic flow. This flow can be observed with the help of either dyes, dust particles, or scattered light. The flow cells so observed usually extend from one electrode to the other and exhibit a domain width dependent on the strength of the applied electric and magnetic field. With increasing elctric field strenght, these flow cells decrease in width and are generated and dissipated more rapidly. Data relating to the average state of alignment as the result of applied electric and magnetic fields is also presented.
