Abstract

Triple-charge-transfer (TCT) spectrometry was used to study the triple ionization of allene (C3H4). Ten clearly defined peaks were observed in the spectra, from which triple-ionization energies to electronic states of C3H43+ were determined. Triple-ionization energies to quadruplet states were calculated using the ADC(2) Green's function method. The calculated values agree well with those measured, thus giving an insight into the electronic transitions which gave rise to the spectral peaks. Quadruplet states were considered since these will be populated if spin is conserved in the triple-electron-capture reactions on which TCT spectrometry is based.
