Description	Abstract: We report the results of a detailed selected ion flow tube (SIFT) study at 300 K of the reactions of the 1-alkene and trans-2-alkene isomers of pentene, hexene, heptene, octene and nonene and I-decene (all liquids at room temperature) with H3O+, NO+ and O-2(+). All 33 reactions proceeded at the collisional rate under these SIFT conditions (helium carrier gas pressure of 0.7 Torr). The H3O+ reactions with both isomers of each alkene proceeded via exothermic proton transfer, which resulted in partial dissociation of the MH+ product ions for the longer chain alkene molecules, M, the number of fragment ions depending on the chain length. However, the mechanisms of the NO+ reactions were isomer specific, those involving the 1-alkenes proceeded via NO+ M production (three-body association) followed by partial stabilisation and partial dissociation of the nascent adduct ion to several products, including ions of the kind RHNO+ (R = CH3, C3H5, C4H7, etc,).
