## Abstract The proton‐coupled ^13^C NMR spectrum of salicylaldehyde was analysed. The second‐order character of the seven independent sub‐spectra allowed the signs of most of the couplings to be determined. The input values for the analyses were obtained from the known __J__(CH) values of benzene,
