Number 25 (Story #4), March, 14 1991 by Phillip F. Schewe and Ben Stein THE MAGNETIC SUSCEPTIBILITY OF CARBON-60 has been measured by a team of scientists at AT&T Bell Labs and Cornell University. They found that the diamagnetism of C-60 is relatively small, implying that C-60 is an aromatic molecule: that is, its hexagonal facets are like a three-dimensional analog of a benzene ring. In contrast to the soccerball-shaped C-60, the egg-shaped C-70 molecule was found to be strongly diamagnetic. Thus the fullerenes as a family do not conform to a single aromatic category.
