Influence of magnetic field on the molecular orientation in epitropic mesophase of nitrobenzene

The influence of magnetic field on the molecular orientation type in epitropic liquid crystalline (ELC) phase of nitrobenzene was investigated by transmitted light ellipsometry method in gap optical lightguide with variable thickness. The outcomes of the experiment allow us to suggest the structure reorganization in wall-adjacent ELC layer of nitrobenzene, similar to Freederickʹs transition in thermotropic LC.
