Abstract: The molecular structures of non-IPR C₄₀ fullerene isomers 31 (C_s), 38 (D₂) and 39 (D_5d) were studied using a semiempirical approach developed earlier for higher fullerenes. Quantumchemical calculations (DFT) showed that they have closed shells. The distributions of single, double and delocalized π bonds in the test isomer molecules and their molecular formulas are presented for the first time.

Keywords: small fullerene, bonds distribution, substructures, radical, strain, fused pentagons.
