Abstract

Modifications of the elastic properties of p-terphenyl (C₁₈H₁₄) have been studied by Brillouin scattering from room temperature down to 80 K. The more important effect produced by this transition at 193 K is the appearance of 3 new elastic constants and it can be explained by a coupling quadratic both in deformation and order parameter.
