TL;DR: In this paper, the NQR spectra of the three isomeric aminopyrides and the five aminomethylpyrides have been analyzed in terms of the electronic populations of the ring-nitrogen pπ and σ orbitals.
Abstract: The nitrogen‐14 nuclear quadrupole resonance (NQR) spectra of the three isomeric aminopyrides and the five isomeric 2‐aminomethylpyrides have been observed. The data is interpreted in terms of the electronic populations of the ring‐nitrogen pπ and σ orbitals. The results show that the amino group is a strong π‐electron donor and, in addition, behaves as a weak σ‐electron donor. A model for the amino group which is consistent with the NQR data is presented.
