Fullerene graphs are trivalent plane graphs with only hexagonal and pentagonal faces. They are often used to model large carbon molecules: each vertex represents a carbon atom and the edges represent chemical bonds. A totally symmetric Kekulé structure in a fullerene graph is a set of independent edges which is fixed by all symmetries of the fullerene and molecules with totally symmetric Kekulé structures could have special physical and chemical properties, as suggested in [1] and [8]. All fullerenes with at least ten symmetries were studied in [4] and a complete catalog was given in [5]. Starting from this catalog in [2] we established exactly which of them have at least one totally symmetric Kekulé structure.

Abstract
Fullerene graphs are trivalent plane graphs with only hexagonal and pentagonal faces. They are often used to model large carbon molecules: each vertex represents a carbon atom and the edges represent chemical bonds. A totally symmetric Kekulé structure in a fullerene graph is a set of independent edges which is fixed by all symmetries of the fullerene and molecules with totally symmetric Kekulé structures could have special physical and chemical properties, as suggested in [1] and [8]. All fullerenes with at least ten symmetries were studied in [4] and a complete catalog was given in [5]. Starting from this catalog in [2] we established exactly which of them have at least one totally symmetric Kekulé structure.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
