The 15 N chemical shift have been measured for α‐ 15 N‐labelled phenylazo‐2‐naphthol and its lithium complex. The change of the 15 N chemical shift on coordination of the azo nitrogen to lithium appears to be related to those of protonation of the same nitrogen. The chemical shifts of azo form and hydrazone form have been calculated according to the weighted δ N and 1 J NH of different fractions. It is concluded that there is a bond formation between Li and N atoms.
