Influence of excited molecules on the process of Frictional flow of Nonassociated liquids

Abstract

It is shown that the viscosity of various nonassociated liquids can be described adequately by taking into account both the influence of the rate of the straight-line formation of holes’ volume caused by irregular jumpings of excited molecules and the increase in the number of bimolecular collisions which is connected with intramolecular conformational transitions in the liquid phase. The proposed equations allow the calculation of this transport property at different temperatures.
