The self-association of acetanilide through hydrogen bonding between N-H and O=C in the solvents [2H1]chloroform, [2H6]acetone, [2H3]acetonitrile and [2H6]dimethyl sulphoxide is investigated by high resolution nuclear magnetic resonance spectroscopy. Dilution shift data for the protons of the N-H group were measured over a wide range of temperature and concentration. The monomer shift, dimer shift and dimerization constant were determined by a graphical method operating on the dilution chemical shift data. The enthalpy and entropy of dimerization were also obtained from the van´t Hoff plot.
