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