[en] The unimolecular dissociation of energy-selected fluoroethene and 1,1-difluoroethene ions has been investigated by threshold photoelectron photoion coincidence TPEPICO) technique. The breakdown diagrams of the 1,1-difluorethene and fluoroethene have been recorded between 13-22 eV. From time-of-flight (TOF) spectra, complete distributions of the kinetic energy released (KERD) in the dissociation of these energy-selected ions have been derived. For the HF-loss reaction channel, the KERD peaks at about 200 meV for low excitation energies but becomes thermal at higher excitation energies. For the F-loss channel, the KERD peaks at zero kinetic energy for low excitation energies but at about 200 meV for high excitation energy. The analysis of the KERD provides evidence that consecutive fragmentation takes place for the 1,1-difluoroethene at energies above 19 eV.
