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 result
s were compared with those obtained by other techniques namely differe
ntial scanning calorimetry, nuclear magnetic resonance and dielectric
relaxation spectroscopy. The transformations glassy phase (I-g) --> pl
astic metastable (I'), plastic metastable (I') --> brittle (II) and br
ittle (II) --> plastic stable (I) were analysed and the obtained resul
ts confirmed the TSDC technique as a powerful tool to study order-diso
rder transitions in molecular crystals.
