The Clar Structure of Fullerenes
… are designed to model carbon molecules. The <em>Clar number</em> and <em>Fries number</em> are two parameters that are related to the stability of carbon molecules. We introduce <em>chain decompositions</em>, a new method to find lower bounds for the Clar and Fries numbers. In Chapter 3, we …

The Structure of 4-Clusters in Fullerenes
… rings for a given Kekule structure is called a Clar set, and the maximum possible size of a Clar set over all Kekule structures is the Clar number of the fullerene. For any "patch" of hexagonal faces in the fullerene away from all pentagonal faces, there is a "perfect" Kekule structure: a Kekule …
