Abstract

Semi-empirical calculations, of varying degrees of sophistication, are effected in order to predict the »London« jr-electron magnetic-properties of several carbon-atom fragments - some large, some small - that are extant on the spherical surface of the truncated-icosahedral C6o cluster known as Buckminsterfullerene. Calculations by the least-approximate of the methods that have been applied predict every one of the Buckminsterfullerene fragments studied to display »London« jr-electron magnetic-properties that are, overall, diamagnetic - to the extent of between ca. 1/3 of, and ca. 5 times, the benzene value.
