The 220 MHz 'H spectra of isoverbanone, nopinone and verbanone are reported. The spectra of the first two are completely assigned but that of verbanone only partially. The coupling constants obtained provide information about the conformation of these molecules. The isoverbanone molecule is almost Y

Abstract
The 220 MHz PMR spectrum of car‐3‐ene (3,7,7‐trimethylbicyclo[4,1,0]hept‐3‐ene) is interpreted and a conformation deduced. In contrast to previous work, which has discussed a highly buckled structure for the 6 membered ring, the present work finds this ring to be essentially planar.
