Abstract
The ground state orientational degeneracy of a system of diatomic pola r molecules disposed on the sites of a planar square lattice is shown to be broken when taking into account the quadrupole interaction. As a result, the corresponding Goldstone mode vanishes and the long-range orientational order is stabilized in accordance with the recent experi mental data.
