Resum
We probe the temperature- and pressure-dependent specific volume (v) and dipolar dynamics of the amorphous phase (in both the supercooled liquid and glass states) of the ternidazole drug (TDZ). Three molecular dynamic processes are identified by means of dielectric spectroscopy, namely the a relaxation, which vitrifies at the glass transition, a Johari-Goldstein ßJG relaxation, and an intramolecular process associated with the relaxation motion of the propanol chain of the TDZ molecule. The lin...
