Abstract
A comparative analysis of experimental data on the orientational order parameter, heat capacity and Gruneisen parameter with those predicted by the mean-field microscopic theory given in the accompanying paper is carried out. The orientation-motion freezing mechanisms driven by t he strain, quadrupolar and reaction fields are identified. It is prove d that within the quadrupolar glass (QG) phase the random-site effects dominate over random-bond dilution effects, The entry to the QG phase is characterized by the freezing temperature, at which the total intr insic field disappears. The QG ground-state distribution function know n from NMR spectroscopy is proposed.
