The 1 H and 13 C NMR spectra of 1‐nitroso‐2‐naphthol and its disodium 3,6‐disulphonate, 2‐nitroso‐1‐naphthol and its sodium 4‐sulphonate and the complexes of the sulphonated ligands with dioxouranium(VI) were recorded and analysed. The results show the nitrosonaphthols exist predominantly in the oxime form, and that the 1‐nitroso compounds have a preferred structure. The quinonoid oxygen does not take part in the complexation with dioxouranium(VI), which is effected by chelation through the oxime oxygen and nitrogen.
