Dissociation of Singly and Multiply Charged Fullerenes: Emission of C4, or Sequential Emission of C2?
Abstract
We have obtained direct mass spectrometric evidence that fullerene ions Cz+60 (z=1, 2, or 3) and Cz+58(z=1,2) undergo unimolecular dissociation by sequential emission of two C2 units, on a time scale of 10−5 s. Moreover, a comparison of experimental and theoretical breakdown graphs reveals that unimolecular formation of C+56 from the C+60 parent ion within a given observational time window is dominated by successive loss of C2; direct C4 loss does not contribute significantly. This conclusion is not affected by uncertainties in our knowledge of the energetics of C2 vs C4 loss. REFERENCES
