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