Aqueous peroxomolybdates have been studied using O-17 NMR together with equilibrium measurements and calculations, over a wide range of conditions. Ten peroxo species are identified, mostly in more than one state of protonation. Some are already known in the solid state, or from equilibrium analysis, but structural information is also obtained for MoO3 (HO2)(-) and the new or previously tentative species Mo2O5 (O-2)(2)(2-), HpMo7O23 (O-2)(2)(p-6) and HpMo7O23 (O-2)(p-6) (p = 0-2). Sites of protonation are identified, as are O-17 resonances from both bidentate and monodentate peroxide. Several oxygen exchange processes are also seen, including a probable dimer-tetramer exchange.
