Notes:
Carbon-carbon coupling constants of 1-phenylazo-2-naphthol and 2-phenylazo-1-naphthol have been measured with the SEMINA-1 pulse sequence. The carbon-carbon couplings provide an unambiguous assignment of the 13C spectra. The magnitudes of the carbon-carbon coupling constants are discussed in relation to the tautomeric nature of the compound. Substituent effects on couplings are also considered.
