Valance bands are out of phase in the ground state for compounds with this property according to the two state model.
The theoretical model for the Stevens rearrangement favors a transition state with this property, while photochemical reactions with this transition state prefer a suprafacial configuration. Compounds possessing this property can be stabilized in transition metal complexes, and Li 4 Al 4 is an all metal species that possesses this property. Valance bands are out of phase in the ground state for compounds with this property according to the two state model. Open chain versions of compounds with this property undergo conrotatory cyclizations according to the Woodward-Hoffman rules. This property is associated with a higher magnetic ? susceptibility exaltation due to the induced paratropic ring current and inner protons are significantly more deshielded than outer protons on rings with this property. For 10 points, identify this property exemplified by planar molecules such as cyclobutadiene which have exactly 4 n pi electrons, disobeying Huckel's rules, and are more unstable than non-aromatic compounds.
