In the C-13 NMR spectra of 5-hydroxy-1,4-naphthoquinon-4-imines the para-quinonimine form is characterized by the presence of signals from C-5 in the region 160-162 ppm and from C-10 at similar to115 ppm whereas typical signals of the ana-quinoid form are those of CS in the region 169-170 ppm and C-10 at 110-11 ppm.
