✦ Synopsis
Spin-spin coupling between 14N and "C nuclei is observed in NMR spectra of some quaternary ammonium compounds, including a series of heterocyclic cations. 'J values are in the range 2.24.2 Hz.
Instances of coupling through two and three bonds are also reported and these are correlated with "C chemical shift data for the structures concerned. 13C, 14N NMR coupling Quaternary ammonium compounds; 'J, 'J and 5J values ' H NMR 19F NMR Configurational assignment /3-Fluoro-/3-phenylamines
