Dissociation of the CF+4 molecular ion has been investigated using monochromatized synchrotron radiation and the energy-selected electron-ion coincidence method. The 2t− 12 C ionic state produces fragment ions CF+2 and CF+3. The branching ratio CF+2/CF+3 is increased by a factor of ˜6 by the C 1s excitation to the lowest unoccupied antibonding orbital, from the ratio at the direct ionization of the 2t−12 orbital. This increase is interpreted in the light of the nuclear motion in the core-excited state, with the help of theoretical calculations based on the vibronic model.
