We present differential optical reflectivity and null transmission ellipsometry data from several mixtures of MHPBC enantiomers. From this data, we have determined the chiral smectic phase sequence as a function of enantiomeric excess. The data suggest a change in the structure of the smectic-[formula presented] phase and the surface tilt state as the enantiomeric excess is reduced. The results also show that the intermediate phases, smectic [formula presented] smectic [formula presented] and smectic [formula presented] disappear sequentially on reducing the net chirality.
