The current status of isomer enumeration of useful benzenoids and a new topological paradigm
Jerry Ray Dias · Journal of Physical Organic Chemistry · 1990
Abstract The enumeration and development of conceptual tools for understanding the chemical properties of practical benzenoid hydrocarbons is stressed. Currently known isomer numbers for benzenoids having up to 60 carbons are summarized. Although there are well over 2 million isomers in this range, only approximately 500 benzenoid hydrocarbons have been characterized.
