Therefore, it would be predicted that for the three double bonds in the Kekule structure, the change in enthalpy would be 3 x -120 = -360 kJ [mol.sup.-1].
thinkthat the source of the stability of it is attributed to the fact that uniquely amongst the 1812 isomers it has a Fries Kekule structure where all hexagons are alternating and all pentagons do not contain any double bond [14].
In graph theory, the Huckel molecular graphs with Kekule structures are graphs with perfect matchings of which the largest degree of vertices does not exceed three.
