摘要：

Systematic Raman scattering investigations were carried out on TPP during the isothermal transformations of the supercooled Liquid into the glacial state, in the 210-230 K temperature range. From these experiments the glaciation process can be interpreted in terms of aborted crystallization. This study reveals that the crystallization aborts in a distinctive stage, i.e., in a glacial state composed of crystallites of the stable crystalline state, characterized by a size strongly dependent on the aging temperature. The size of crystallites can be considered in the nanometric or micrometric scale if the glacial state is prepared, respectively at the low or at high temperature in the 210-230 K range. The time of transformation into the glacial state is also observed as drastically dependent on the aging temperature.
