Determination of association constants for weak solute–solute complexes by nuclear magnetic resonance spectroscopy Original Research Article

Standard methods for the determination of association constants by nuclear magnetic resonance spectroscopy are adapted for weak complexes that interact only by van der Waals forces. The association constants and the corresponding changes in Gibbs free energy are determined for the self-association of anthracene and the mixed association of anthracene with dodecane in deuterated methanol.
