In addition to the aforementioned Mobius type, electrophilic substitution on compounds with this property quantified by the Pariser-Parr-Pople method proceed through arenium ion intermediates, and they can interact with each other via pi-pi stacking.
Barrelene exhibits a variation to this phenomenon in which molecules have an odd number of subunits in a monocyclic array. Armstrong's inner cycle is a pictorial representation of this, and tropone is a compound with properties like this phenomenon. A method using the zero-differential overlap approximation takes into account electronic correlation, and such compounds are far downfield in NMR spectra due to a unique electronic feature known as the ring current. In addition to the aforementioned Mobius type, electrophilic substitution on compounds with this property quantified by the Pariser-Parr-Pople method proceed through arenium ion intermediates, and they can interact with each other via pi-pi stacking. Kekule created a model for the simplest of these compounds which was later modified by resonance theory. For 10 points, name this chemical property exemplified by benzene that is governed by Huckel's rule.
