Ion cyclotron single- and multiple-resonance spectroscopy have been used to identify and examine the energetics of ion-molecule reactions in which H3O+ and H3S+ are involved either as product or reactant. The reactions observed provide narrow limits for the gas-phase proton affinities of these species, giving 164 ± 4 kcal/mole for H2O and 178 ± 2 kcal/mole for H2S.
