摘要：

Nitromethane (and other nitroalkanes) added to methanol with or without CCl4 dilution suppresses exchange of the OH proton owing to the formation of strong intermolecular NO2-HO hydrogen bonds. This prolonged residence time for exchange of the OH proton is sufficient to allow the detection of spin-spin coupling (JHCOH) for the alcohol protons. The observed variability in the displacement of the OH resonance effected by CH3NO2 was interpreted in terms of complex formation. Extensive dilution studies (CCU) of CH3NO2-CH3OH mixtures provided evidence for the formation of several discrete complexes of this donor-acceptor pair. © 1969, American Chemical Society.
