摘要：

Comparative study of near edge X-ray absorption fine structure spectra (NEXAFS) of fluorinated fullerenes C60Fx (x = 0, 18, 36) has been implemented. Local density of unoccupied states was obtained and an accurate boundary between pi* and (pi+sigma)* states was determined. The experimental evidence was found that unoccupied pi*- states of C60Fx are delocalized ones and form cluster shells that sequentially disappear in fluorination starting from the highest state. As a result, the density of the lowest pi* - state (LUMO) was revealed to remain being constant in fluorination despite the pi -electron subsystem exhaustion.
