Description
Fluorescence spectra of the A2Πu--X2Πg system of CO+2 and CS+2 ions, following electron impact on supersonic jet targets of CO2 and CS2, have been analyzed to determine vibrational populations. The vibrational distributions of the A2Πu state of CO+2 and CS+2 were found to be independent of the impact energy in the 30--300 eV range. The distribution of the CO+2(A) 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 CS+2(A) state is significantly different from the PES data. This non-Franck--Condon behavior for formation of CS+2(A) in the electron impact is discussed
