C60Br24 as a chemical illustration of graph theoretical independence
Abstract
If it is assumed that the final product of bromination of C60 will obey two rules, (i) that no two sp3 carbons may be adjacent and (ii) that the molecule must have a closed π shell, the experimental Th structure of C60Br24 is uniquely selected from 300, 436, 595, 453, 640 possibilities.
