Abstract

The concentration dependence of the H2O spectra in solutions of tetrabutylammonium bromide Bu4NBr in methylene chloride was investigated by IR-spectroscopy. At low salt and H2O concentrations the equilibrium: Br −f +HOHf⇌Br−⋯HOH dominates where f indicates free or not hydrogen-bonded Br− and H2O. With increasing salt content, Br−⋯H−O−H⋯Br− complexes are present in addition. At high salt and H2O content, including the saturated aqueous Bu4NBr solution, H-bonded cyclic dimers seem to be important.
