## Reliable assignments were made for a series of nitro and amine C ring-substituted dehydroabietic acid derivative, the main resin acid present in disproportionated rosin and an important intermediate in the chemical industry. A combination of 1D and 2D NMR techniques, including HETCORR, COSY and
## Abstract Assignment of the carbon resonances in nine derivatives of __N__‐hydroxybenzotriazole has been carried out. The ^13^C NMR method enables tautomeric __N__‐hydroxy and __N__‐oxide and isomeric __O__‐ and __N__‐acyl structures to be identified. In DMSO, the predominant tautomer of __N__‐hy
## Abstract Complete ^13^C and ^1^H NMR spectral assignments for a series of derivatives of the naturally occurring C‐ring aromatic diterpene resin acid dehydroabietic acid have been made. The use of a combination of 1D and 2D NMR techniques allowed mostly unambiguous assignments of all ^13^C reson
