Refractive Indices of the MHPB(H)PBC and MHPB(F)PBC Antiferroelectric Liquid Crystals

MHPB(H)PBC and MHPB(F)PBC were studied by means of refractometric measurements. The refractive indices: n " (T), n Á (T) and n I (T) were measured using combined methods, applying both appropriately prepared Abbe refractometer and interference wedge. Values of the n " (T), n Á (T) for the...

Description
Summary:MHPB(H)PBC and MHPB(F)PBC were studied by means of refractometric measurements. The refractive indices: n " (T), n Á (T) and n I (T) were measured using combined methods, applying both appropriately prepared Abbe refractometer and interference wedge. Values of the n " (T), n Á (T) for the Sm A*, Sm C* and Sm C A * phases are related to the optical axis perpendicular to the proper smectic planes. The results of the optic measurements were discussed.
