Hydroxy-1-methyl-4-isopropylcyclohexene carveol

The correlation signals of the INADEQUATE experiment directly build up the ring skeleton A of the compound. Here characteristic 13C shifts (8C = 123.1, 137.6 148.9, 109.1) establish the existence and position of two double bonds and of one tetrahedral C-O single bond (Sc = 70.5). DEPT spectra for the analysis of the CH multiplicities become unnecessary, because the INADEQUATE plot itself gives the number of CC bonds that radiate from each C atom. 

The CH connectivities can be read off from the CH COSY plot thus the complete pattern B of all //atoms of the molecule is established. At the same time an OH group can be identified by the fact that there is no correlation for the broad signal at SH = 4.45 in the C//COSY plot.
