Abstract
Starting from the original model of Adam and Gibbs, which gives a relationship between the structural relaxation time tau and the configurational entropy, an equation to describe the temperature and pressure behavior of tau has been recently derived. Herein a test of the validity of this new equation is presented by means of dielectric, calorimetric and volumetric data. (C) 2002 Elsevier Science B.V. All rights reserved.File in questo prodotto:
