Comments:

The carbon shift prediction for this seven membered ring with three double bonds and two nitrogen containing side-groups remains challenging. Additivity rules are applicable to all of these carbons. But some of them have no HOSE code of three or more spheres, which would obtain a more accurate shift prediction.
