✦ Synopsis

Extracts of grapbitic soot are shown by electron attachment mass spectrometry to contain, in addition to the well-known fullerenes C, and Go. smaller quantities oflarger carbon clusters, up to C 2o. A structure for one of the more abundant clusters, G6, is proposed. The data show the conspicuous absence of particular clusters. The relative stabilities oft&, C,O and CM were investigated by charge exchange and collision activated dissociation experiments. All the fullerene ions showed remarkable stability to fragmentation. At the highest collision energies accessible, fragmentation of C$J and C, produced a series of products fmm Cz loss, including the conspicuous formation of Cso ions.
