The 2-norbornyl cation is a 
-complex, not a
-bridged, nonclassical species: an AIM study.

The 2-norbornyl cation is not a nonclassical,
-bridged species but a
-complex. This was revealed in a new
atoms in molecules
(AIM) study of the topology of its charge density. Similarly, there is nothing
nonclassical about the 2-bicyclo[2.2.2]octyl cation.
