Abstract

The scaling of the dielectric and electric relaxation in two low molecular weight glass forming systems (PDE=Phenolphtalein-dimethylether and KDE=Kresolphtalein-di-methylether) is studied in the frequency regime from 10-3 Hz to 109 Hz by use of broadband dielectric spectroscopy. For both the dielectric α-relaxation and the dc-conductivity the temperature dependence is characterised by a crossover (at a temperature TA) from an Arrhenius to a Vogel-Fulcher-Tammann law. Above TA the dc-conductivity (reflecting translational diffusion of mobile charge carriers) and the α-relaxation have the same temperature dependence. Below TA a decoupling is found in agreement with recent tracer diffusion experiments (M. Lohfink and H. Sillescu, in: Proc. of the 1st Tohwa University Int. Symp., Fukuoka, Japan, 4–8.11.1991, Am. Inst. Phys. Conf. Series). For the α-relaxation, the relaxation time distribution shows a pronounced temperature dependence below TA, while it is only weakly varying with temperature above TA.
