Results of spectrophotometric research of the association of riboflavine and sodium salicylate molecules in aqueous solution are presented. Experimental data was analyzed using a dimer model of association of molecules. The experimental spectrum of absorption of a mixture of heterocyclic molecules was decomposed into individual components by the means of the regularization method. The quantitative information on structure of molecular complexes according to separate components of a range, specifically distance and corners between electrical dipole moments of transitions of molecules is obtained.
