Nuclear Quadrupole Resonance of Some Four‐Coordinated Nitrogen Compounds

Nitrogen‐14 nuclear quadrupole resonance spectra have been obtained from several substituted ammonium ions. The data are interpreted in terms of the electronegativity of the substituents, and a relative scale for H, CH3, NH2, NH3+, and OH is obtained. The enhanced proton‐nitrogen spin‐spin coupling was utilized to match unequivocally the v+ and v− spectral lines for each nitrogen‐14 site.
