Temperature relationships of chemical shifts of protons of proflavin mixed with deoxytetraribonucleoside triphosphate 5'-d(ApGpCpT) in water solution were investigated on impulse NMR spectrometer (500 MHz). Procedure is suggested for calculating values of mole fractions of various associates in solution as a function against temperature. Free energies of Gibbs, entalpy and entropy were determined in the reactions of complex formation 1:1, 1:2, 2:1 of proflavin with tetranucleotide. The results point to a significant role of hydrophobic interactions during the formation of dye--tetramere duplex complexes.
