Abstract
The radical cation of the fullerene series C60, C70,C76, C78 and C84 were generated in oleum (fuming sulphuric acid with 30% free SO3) and analyzed by electronic absorption spectroscopy. A general agreement was found between the fullerenes radical cation spectra generated in oleum and those described in the literature and produced in other conditions. An attempt to correlate the radical cation transition of C60, C70, C76, C78 and C84 in oleum with their ionization potential was proposed.
