A selected ion flow tube study of the reactions of H3O+, NO+ and O2+ with a series of C5, C6 and C8 unsaturated biogenic alcohols

Based upon the measured product ion distributions, it can be concluded that in some particular cases the NO+ or O2+ precursor ions are appropriate to identify and quantify isomers in mixtures of the unsaturated alcohols studied. Especially in leaf wounding experiments, during which cis-3-hexen-1-ol and trans-2-hexen-1-ol are emitted, the chemical ionization technique, based upon the NO+ or O2+ precursor ion, may be a valuable diagnostic tool to distinguish and quantify these isomeric forms.
