Abstract
Thermally Stimulated Current (TSC) spectroscopy and Differential Scann ing Calorimetry (DSC) have been applied to the characterization of the microstructure of a pharmaceutical drug. The dielectric relaxation sp ectrum shows two modes located in the temperature range of the glass t ransition. They have been attributed to the molecular mobility in the ''true amorphous phase'' and in the <<rigid amorphous region>>.
