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
