Opis The 12,500 Kekulé valence structures of Buckminsterfullerene C60, of which only 158 are symmetry distinct, show large variation in their forms and characteristics. We display all 158 symmetry distinct Kekulé valence structures which have been classified according to their innate degree of freedom (df), which varies from the maximal value of df = 10 to df = 5. The most important and unique Kekulé valence structure in which CC double bonds are exocyclic to pentagonal faces belongs to df = 10, while there are 36 symmetry distinct Kekulé structures associated with df = 5.
Od 12.500 Kekuléovih valentnih struktura Buckminsterfullerena samo je 158 različitih ako se razmatraju samo strukture koje su različite u odnosu na operacije simetrije. Kekuléove valentne strukture klasificirane su preme stupnju slobode (df), koji se mjenja od maksimalne vrijednosti df = 10 pa do df = 5. Najvažnija i jedinstvena
Kekuléova valentna struktura u kojoj su sve CC dvostrukle veze izvan peteročlanih prstena ima stupanj slobode 10, dok broj različitih Kekuléovoh struktura obzirom na simetriju ima 36 kojim pripada stupanj slobode 5.
