A selected ion flow tube study of the reactions of small CmHn+ ions with O atoms

The reactions of thirteen CmHn+ ions (m⩽6) with atomic and molecular oxygen and nitric oxide have been measured using a selected ion flow tube operating at room temperature. Rate coefficients and product distributions are reported for each reaction. Most of the hydrocarbon ions studied exhibit relat...

Zusammenfassung:The reactions of thirteen CmHn+ ions (m⩽6) with atomic and molecular oxygen and nitric oxide have been measured using a selected ion flow tube operating at room temperature. Rate coefficients and product distributions are reported for each reaction. Most of the hydrocarbon ions studied exhibit relatively rapid reactions with O atoms and proceed at substantial fractions of the collision rate. All O atom reactions showed multiple product channels and the formation of a –C–O bond, either in the ion product or the neutral product of reaction.
