lines associated with the equivalent/inequivalent nitrogen atoms having unpaired
electrons in the substituent groups are shown on the horizontal axis for convenience.
These spectra were reproduced using the principal values of the g and A tensors of
unpaired electrons, along with line width parameters and signal amplitudes. The g
