Abstract

AbstractWe report the resonance energies (REs) of several fullerenes with 4‐membered rings and their isomers with only 5‐ and 6‐membered rings computed using the conjugated‐circuit model [RE(CC)] and the topological resonance energy (TRE) model. Both aromaticity indices were normalized by dividing by the size of the considered fullerene [RE(CC)/e and TRE/e]. The results parallel the predictions by Gao and Herndon using the much more advanced SCF–UHF π‐electron approach. A good linear correlation is found between the topologically defined indices [RE(CC)/e and TRE/e] and normalized SCF–UHF π‐electron energy. © 1995 John Wiley & Sons, Inc.
