摘要：

The variation of order parameter with temperature has been studied by following the intensity of Raman lines forbidden in the high-temperature phase. The two-dimensional character of the transition is confirmed. Remnant scattering above Tc indicates the presence of molecular layers possessing low-temperature phase symmetry.
