Structures and IUPAC Rules for Nomenclature

Over the decades several significantly different PAH and PAC numbering/nomenclature systems have been proposed and widely used in the older literature, e.g., that of Clar (1964). Unfortunately, even today this can lead to confusion on the part of those unfamiliar with the history of different systems of nomenclature. 

We follow the 1979 IUPAC recommendations summarized in Polynuclear Aromatic Hydrocarbons Nomenclature Guide (Loening et al. 1990). The American Chemical Society also publishes the Ring Systems Handbook, which, ca. 1990, contained structural diagrams for over 70,000 unique ring systems (American Chemical Society, 1977 to present). 

A detailed discussion of these rules and nomenclature is beyond the scope of this book. However, we
