Notes:
The magnitude of 1J(15N13C) in para-substituted benzenediazonium ions has been used to assess the importance of the several resonance forms contributing to the ground state of the ion. From a comparison of values observed in 4-nitro- and 4-dimethylamino-benzenediazonium ions and their respective 3,5-dimethyl derivatives, it is concluded that diazo-type structures are important only with strong electron-releasing substituents in the aromatic ring. INDO-SOS-MO calculations indicate that the large and negative Fermi contact term dominates this interaction.
