Relaxational features of supercooled and glassy m-toluidine

Recent investigations performed by dielectric and mechanical spectroscopy have provided detailed information about the dynamical response of m-toluidine in the supercooled and glassy states. In the present work we analyze the properties of the alpha-relaxation process on the basis of dielectric and shear mechanical data, discussing the unusual behavior of this fragile glass-former. The nature of the secondary relaxation is elucidated by high resolution dielectric measurements and discussed in terms of the Coupling Model and literature results on other small molecule glass-forming liquids.
