Abstract
Data are presented on the dielectric relaxation in supercooled liquid glycerol. These data span over 14 decades in frequency from 10 −4 Hz to 2×10 10 Hz. It is found that the peak in the imaginary part of the dielectric susceptibility has a temperature dependence that can be fit with a Vogel-Fulcher form: v = v 0 exp[− A /( T − T 0 )]. The shape of the response function in the high frequency tail cannot be fit with a stretched-exponential form. However the data can be scaled onto a single master curve which has previously been shown to fit a number of other glass-forming liquids.
