A model of comb-like association with branches of arbitrary lengths: The mean statistical anisotropy of the polarizability tensor of liquid molecules

Analytic methods for calculating the mean anisotropy of the polarizability of liquid molecules consisting of chain aggregates of arbitrary lengths and branched comb-like aggregates with branches of arbitrary lengths were developed. The dependences of the mean anisotropy of the polarizability of methanol molecules on the thermodynamic parameters (equilibrium constants) of chain and branched aggregation and the structural characteristics of supramolecular aggregates were calculated. Special attention was paid to the influence of the degree of branching of comb-like aggregates on anisotropic light scattering. The calculation results were compared with the experimental data.
