SPECTROSCOPIC STUDY OF THE PROCESS OF HYPOCHROMIC EFFECT IN SOLUTIONS OF NATURAL DYES AND VITAMIN B2

The process of self-assembly of riboflavin molecules in aqueous and binary mixtures of solvents was investigated by the spectroscopic method. It was shown that during the assembly of vitamin B2 molecules, dipole-dipole interaction occurs, as a result of which resonant splitting of excited electronic levels of riboflavin molecules occurs. And the observable hypo chromic effect is due to a decrease in the intense absorption capacity of the aggregated riboflavin molecules themselves
