6. The sample was purchased from MER Corporation.
7. 84 isomers, along with unreacted DMA. Fractions 2-4 were brown and were DMA products of fullerenes.
8. 78 disappeared in each fraction and that numerous new peaks appeared due to their DMA adducts between -11 ppm and -21 ppm.
9. 84, respectively.
10. 82 isomer, consistent with Shinohara and co-workers' work in ref 3.
