Valence bond (VB) formulas or Schlegel diagrams are useful for simple schematic representations of fullerenes and their derivatives. VB formulas are mostly used for parent fullerenes or for derivatives with a few modifications of the cage structure only. A Schlegel diagram shows each C-atom of the fullerene, which is flattened out in two dimensions. This model is suitable for considering polyadducts, for example, polyhydrofullerenes.

The question about the isomeric composition of the synthesized samples of the C6QH36 fullerane have not been completely resolved yet. In this work we consider ten C60H36 isomers, which are often formed under the synthetic conditions (Haufler et al. 1990 Ruchardt et al. 1993 Lobach et al. 1997 Billups et al. 1997 Guo and Scuseria 1992 Okotrub et al. 1999 Nossal et al. 2001). Their point groups are T, Th, D3d, Z>3d, S6 (Nos. 91 and 88), C3 (Nos. 3, 4 and 64) and Cv The Schlegel diagrams of the considered isomers are demonstrated in Fig. 4.5, the numbering follows (Clare and Kepert 1994, 1999).
