摘要：

A mass-spectrometric study of ion-neutral reactions occurring in COa 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 CO+ in these experiments. Reaction of C0+ with CO2 is found to be somewhat faster than previously reported. An approximate rate has been obtained for loss of C02*+. The great abundance of C2O4+ in this system at pressures near 1 torr results from reaction of C2O4+ 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 C-4Ot+ is suggested.
