Molecular motions and phase transformations in solid 1-cyanoadamantane: A thermally stimulated discharge currents study

The molecular motions associated with different phase transformations in 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 dielectric relaxation 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.
