The structure of C1 s and F1 s core electron levels in C 60 F 18 and C 60 F 36 fluorinated fullerenes has been studied by X-ray photoelectron spectroscopy using synchrotron radiation. It is established that C1 s levels of carbon atoms not bound to fluorine in these compounds are shifted down by 1.0 and 1.6 eV relative to the C1 s level in the usual C 60 fullerene, so that the binding energies of the core electron levels in C 60 F 18 and C 60 F 36 amount to E b (C1 s , C-C) = 285.7 and 286.3 eV, respectively. These values are characteristic and can be used for the identification of both homogeneous fluorinated fullerenes and combined materials comprising a mixture of various fluorinated fullerenes with each other and with different carbon-containing based materials.
