Enumeration of Kekulé Structures in Defective Patterns of Rectangular Graphite
István Lukovits
Abstract
The number of Kekulé structures is an indicator of the aromatic character of the underlying polybenzenoid. Graphite is a polybenzenoid. In this paper, a new algorithm is proposed for determining the number of Kekulé structures in rectangular graphite and its incomplete and defective variants. Defective patterns model functionalized structures. Moderate functionalization will cause a slight increase in the aromatic properties of the underlying patterns.
