Abstract
Difluorinated higher fullerenes have been studied by Knudsen cell mass spectrometry. Thermal negative ions CnF2-, (n = 60, 70, 72, 74, 76 an d 78) were produced inside the effusion cell as well as the neutral mo lecules C60F2 and C70F2. From the equilibrium constants for the electr on exchange reactions between difluorinated fullerenes and their paren ts electron affinity values were derived for C60F2 (2.74 eV) and C70F2 (2.80 eV).
