Abstract
For a description of the HTP with quantities determined by structural elements of a molecule, the chirality interaction tensor has been introduced. The diagonal elements of
with respect to the principal axes of the order tensor of some unbridged 1,1′-binaphthyls have been determined from the temperature dependence of the HTP and that of the order tensor. The distinct smaller W

* (i=1,2,3) of unbridged 1,1′-binaphthyls in comparison to those of bridged 1,1′-binaphthyls can be explained as a result of an ordering phenomenon originated by the large amplitude motion about the dihedral angle φ of the naphthyl-naphthyl bond. There is no necessity to assume a chiral zero for the diagonal elements of
for conformers with a dihedral angle between 0° ≤ φ ≤ 180°.
