 note = {Fluorescence spectra of the Ã2Πu–X2Πg system of CO2+ and CS2+ ions, following electron impact on supersonic jet targets of CO2 and CS2, have been analyzed to determine vibrational populations. The vibrational distributions of the Ã2Πu  state of CO2+ and CS2+ were found to be independent of the impact energy in the 30–300 eV range. The distribution of the CO2+ (Ã) state is very similar to the result obtained by He i photoelectron spectroscopy (PES), which is a Franck–Condon-type vertical ionization, whereas that of the CS2+ (Ã) state is significantly different from the PES data. This non-Franck–Condon behavior for formation of CS2+ (Ã) in the electron impact is discussed. The Journal of Chemical Physics is copyrighted by The American Institute of Physics.},
