Electrospray time‐of‐flight mass spectrometry was used to study dilute (10 −3 M ) solutions of tungstate, vanadate and perrhenate oxyanions under acidic and basic conditions. The electrospray mass spectra of tungstate and vanadate solutions indicate the presence of protonated monomeric oxyanions in basic solution (pH ≈ 10) and protonated polymeric species in acidic solutions (pH ≈ 4). Monomeric perrhenate was the only species detected in both acidic and basic perrhenate solutions. For all three systems, the core metalate species detected by electrospray were consistent with reported speciation in aqueous solutions. Copyright © 2000 John Wiley & Sons, Ltd.
