Pw. Fowler et al., C60BR24 AS A CHEMICAL ILLUSTRATION OF GRAPH-THEORETICAL INDEPENDENCE, Journal of the Chemical Society. Perkin transactions. II (Print), (7), 1998, pp. 1531-1533
If it is assumed that the final product of bromination of C-60 will ob
ey two rules, (i) that no two sp(3) carbons may be adjacent and (ii) t
hat the molecule must have a closed sl shell, the experimental T-h str
ucture of C60Br24 is uniquely selected from 300, 436, 595, 453, 640 po
ssibilities.
