Three groups of alkyl-substituted naphthazarins were studied by 'H and "C NMR in chloroform-d at ambient temperature. Preliminary 'H NMR studies were carried out on selected members of each group at low temperatures (down to -120 "C) in dichloromethaue-d, solution. Monoalkylnaphthazarins were found
