Abstract

The concentration dependence of the apparent molar absorptivity of 5'—AMP in ultraviolet and infrared spectra as well as the chemical shifts of H—2, H—8 and H—l' in NMR have been measured. Besides, molecular self—diffusion coefficients through Fourier transform NMR have been taken from the literature. All these data have been separately fitted to an isodesmic indefinite aggregation model to calculate the association equilibrium constants. The influence of the concentration range used upon the association constant values is discussed. The study of very dilute solutions by ultraviolet spectroscopy shows that a dimerization equilibrium is a previous step for the formation of higher aggregates.
