Two‐dimensional NMR of sesquiterpenes. 8—complete assignment of 1H and 13C NMR spectra of seven sequiterpene alcohols from Neocallitropsis pancheri

Abstract
The complete assignment of the proton and carbon NMR spectra for seven sequiterpene alcohols isolated from the heartwood oil of Neocallitropsis pancheri, namely, α, β‐ and γ‐eudesmol, carissone, guaiol, bulnesol and elemol, was achieved using the concerted application of one‐and two‐dimensional NMR techniques including DEPT, COSY, HETCOR and HMBC spectroscopy. The parameters previously reported in the literature were found to be often wrong or incomplete.
