Chemistry of the Fullerenes: The Manifestation of Strain in a Class of Continuous Aromatic Molecules
Abstract
Within the π-orbital axis vector theory, the total rehybridization required for closure of the fullerenes is approximately conserved. This result allows the development of a structure-based index of strain in the fullerenes, and it is estimated that about 80 percent of the heat of formation of the carbon atoms in C 60 may be attributed to a combination of σ strain and steric inhibition of resonance. Application of this analysis to the geometries of structurally characterized organometallic derivatives of C 60 and C 70 shows that the reactivity exhibited by the fullerenes may be attributed to the relief of a combination of local and global strain energy. C 60 is of ambiguous aromatic character with anomalous magnetic properties but with the reactivity of a continuous aromatic molecule, moderated only by the tremendous strain inherent in the spheroidal structure.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
