13. A free energy similar to ours was used by P.K. Mukherjee, J. Chem. Phys. 117, 7788 (2002) to investigate first order I-A and I-C transitions. However, they ignored the biaxiality of the orientational order parameter and incorrectly claimed that the C phase is stabilized by the g2 term. This last mistake led them to exclude the h term, which is necessary to stabilize the C phase. JCPSA6 0021-9606 10.1063/1.1509055
