Testing models for structural relaxation of viscous liquids by temperature jump experiments
Abstract
Based on the Tool-Narayanaswami formalism for structural relaxation we propose an experiment which independent of the relaxation time distribution determines the structural relaxation rate by subtracting relaxations following two different temperature jumps. In particular, the experiment makes it possible to evaluate the relaxation rate immediately following a temperature jump - thus allowing one to distinguish the entropy model from others.
