Abstract

The molecular motions associated with different phase transformationsin the solid state of 1-cyanoadamantane have been studied by thermally stimulated discharge current technique (TSDC) and the obtained results were compared with those obtained by other techniques namely differential scanning calorimetry, nuclear magnetic resonance and dielectricrelaxation spectroscopy. The transformations glassy phase (I-g) --> plastic metastable (I'), plastic metastable (I') --> brittle (II) and brittle (II) --> plastic stable (I) were analysed and the obtained results confirmed the TSDC technique as a powerful tool to study order-disorder transitions in molecular crystals.
