Abstract

Structural-relaxation data in liquids indicate the presence of a distributed relaxation-time spectrum. A physical model for this distribution is proposed. The model is used to calculate the dynamical behavior of fluctuations in an order parameter describing the local liquid structure. This is used to predict both compressional and shear relaxation dynamics. The equation of motion for the ordering parameter includes explicitly both the effects of an elementary rate process and simple diffusion. The calculated distribution of relaxation times for compressional strain is similar to a Cole-Davidson distribution function with a width parameter near 0.5. The predictions for the frequency dependence of the compressibility and shear rigidity agree reasonably well with experimental data in a number of liquids.
