Counting Disconnected Structures: Chemical Trees, Fullerenes, I-graphs, and others

Abstract

When counting isomers with a given number of atoms one usually assumes that we want to count (connected) molecules. In this note we present a method that can be used for counting disconnected structures if counts of connected structures are given. The method can be used also in the reverse direction. If the numbers of all structures are known, the number of connected structures can be readily determined.
