High-resolution calorimetric data for several compounds exhibiting the hexatic-B–smectic-F transition have been obtained. This transition involves the formation of tilt in the presence of bond orientational order. Like most of the smectic-A–smectic-C transitions, which show no bond orientational order, the heat-capacity anomaly of the hexatic-B–smectic-F transition exhibits mean-field-like behavior and can be well described by an extended mean-field model.
