Abstract
AbstractElectrospray ionization tandem mass spectrometry with collision‐induced dissociation (ESI‐MS/MS) was utilized to study the gas phase fragmentation of uranyl peroxide nanoclusters with hydroxo, peroxo, oxalate, and pyrophosphate bridging ligands. These nanoclusters fragment into uranium monomers and dimers with mass‐to‐charge (m/z) ratios in the 280–380 region. The gas phase fragmentation of each cluster studied yields a distinct UO6− anion attributed to the cleavage of a uranyl ion bound to 2 peroxide groups, along with other anions that can be attributed to the initial composition of the nanoclusters.
