14N nuclear quadrupole resonance in compounds containing N–O bonds. I. Oximes

Abstract
The nitrogen-14 nuclear quadrupole resonance spectra at 77°K of thirteen oximes are reported and analyzed in the framework of the Townes and Dailey theory. The results obtained suggest that in most cases the π charge at the nitrogen atom is sufficiently large to allow a positive coupling constant for the nitrogen atom. A weak dependence between the distribution of σ charges and the π charge at the nitrogen atom was observed and is interpreted as arising from hydrogen bonded intermolecular interactions.
