14N nuclear quadrupole resonance studies of 1,8-bis(dimethylamino)naphthalene

The presence of four resonance peaks from two nitrogen atoms in the 14N nuclear quadrupole resonance (NQR) spectrum of 1,8-bis(dimethylamino)naphthalene (DMAN) confirms the asymmetry of this molecule in the crystal. Spectroscopic parameters such as transition frequencies as well as the asymmetry par...

Zusammenfassung:The presence of four resonance peaks from two nitrogen atoms in the 14N nuclear quadrupole resonance (NQR) spectrum of 1,8-bis(dimethylamino)naphthalene (DMAN) confirms the asymmetry of this molecule in the crystal. Spectroscopic parameters such as transition frequencies as well as the asymmetry parameters of the electric field gradient (EFG) tensors and differences in sigma bond occupation numbers have been assigned to particular nitrogen atoms in the molecule.
