title: Novel gas-phase ion-molecule aromatic nucleophilic substitution in beta-carbolines.
abstract: We report a novel gas-phase ion-molecule aromatic-nucleophilic substitution reaction between beta-carbolines and water vapour, that accounts for the observation of ions with higher masses than the precursor ion in the MS/MS spectra.
