Abstract : A mass spectrometric study of ion-neutral reactions occurring in CO2 subjected to electron impact yields rates in agreement with previous studies for reaction of C(+) and O(+) with CO2. Charge transfer from O(+) to CO2 is believed to compete with formation of O2(+) in these experiments. Charge transfer from CO(+) to CO2 is found to be somewhat faster than previously reported. An approximate rate has been obtained for loss of CO2(++). The great abundance of C2O4(+) in this system at pressures near 1 torr results from reaction of CO2(+) with several CO2 molecules. This reaction is not well understood but a mechanism involving stepwise ion polymerization followed by collision induced decomposition of the complex to C2O4(+) is suggested. (Author)
