Hydrogen bonding to divalent sulfur

Author affiliations


A combination of vapor phase infrared spectroscopy and ab initio calculations has been used to show that sulfur is weaker than, but nearly equivalent to, oxygen as a hydrogen bond acceptor. Enthalpies of hydrogen bond formation were obtained for the hydrogen bonded complexes formed between methanol and either dimethyl sulfide or dimethyl ether by temperature dependence studies of the infrared spectra.
