Abstract
This study investigates the association of 2-isopropylphenol through hydrog en bonding in carbon tetrachloride, [H-2(6)]acetone, [H-2(3)]acetonitrile a nd [H-2(6)]dimethyl sulphoxide by using high resolution nuclear magnetic re sonance spectroscopy. Chemical shifts of the hydroxyl proton were measured over a wide range of temperature and concentration. The chemical shift data were treated by a graphical method to determine the monomer shift, dimer s hift and dimerization constant. The enthalpy and entropy of dimerization we re determined via a van't Hoff plot from the temperature variation of the d imerization constant.
