We tentatively interpret these effects as a result of breaking of the dipole-dipole correlations which manifests itself differently in these liquid crystalline phases. The high dipole moment represented by cis orientation probably due to the destabilising through-space interactions of the lone pairs of oxygen atoms yields much greater energy differences such as C-F conformations. Hence, for 1,2,3, trichloro benzene the dipole moment is high compared to others (2.39 D) and for the 1,2,4 trichloro benzene, the dipole moment is 1.26 D.
