摘要：

Hydrogen and carbon-13 NMR chemical shifts of five complexes of 4,8-bis(dimethylamino)naphthalene with strong acids were measured in acetonitrile-d3 and nitromethane-d3 and identified by 2D, NOE difference and long-range enhanced COSY spectra. The assignments of the resonances corresponding to H-2,7, H-4,5, C-3,6 and C4,5 obtained in this study differ from those reported previously.
