## Abstract The reaction of methyl radicals with atomic and molecular oxygen was studied with a photoionization mass spectrometer. The methyl radicals were generated by reacting oxygen atoms with ethylene in a fastβflow tube reactor. The rate constant for the reaction of methyl radicals with oxygen

We describe a new ion source in which a nozzle beam of neutral molecules is ionised by an electron beam and the resulting molecular ion beam is studied by microwave spectroscopic methods. This ionisation technique results in significant population of the near-dissociation levels of the molecular ion
Several orders of magnitude enhancements in the rate constants for three slow ion-molecule reactions with Hz have been observed when the H2 is vibrationally excited. The atomic cations C+, He+, and Ne+ were all observed to react near their respective Langevin rates with vibrationally excited HZ.
