The Influence Of The Secondary Relaxation Processes On The Structural Relaxation In Glass-Forming Materials

In the frame of fractional-kinetic approach, the model of the structural alpha-relaxation in the presence of the secondary beta-relaxation processes is suggested. The model is based on the rigorous bond between beta-processes with alpha-process and leads to the generalized and justified expression for the complex dielectric permittivity (CDP). It allows to form a new sight on the problem of the fitting of multi-peak structure of the dielectric loss spectra in glass-forming materials. The consistency of the CDP expressions obtained is based on a good fit of experimental data for binary methanol-water mixtures. (C) 2013 AIP Publishing LLC.
