IF planarity can be affimmd in the fully unsaturated cycles of the type (I) and (II), pm spectra measured in these groups of ~compounds are expected to show a striking coetrastl, since (I) would be aromatic, exhibiting a diamgnetic ring current. provided n is 2, 4, 6\*\*., and antiammatic, if n is 3
