• 2D-INADEQUATE NMR was used for structure eludication and complete assignment of the carbon signals of nine longifolene isomers. It is shown that at 9.4 T the connectivity of sesquiterpene carbon skeletons can be derived in a single experiment within a few hours, even when three membered rings, aliphatic and olefinic carbon atoms are present and ^1J(C,C) varies between 10 and 70 Hz. A significant reduction of the spectral recording time results if the 2D-INADEQUATE sequence is combined with polarization transfer techniques and the particular relaxation behaviour of the satellites is taken into account. The high value of this procedure for structure eludication of sesquiterpenes and carbon skeletons in other natural products is demonstrated.
