Unravelling the Complexities of Polyoxometalates in Solution Using Mass Spectrometry: Protonation versus Heteroatom Inclusion.

The article presents a study on the use of mass spectrometry in the study of polyoxometalates solutions. It mentions that the determination of the structures of polyoxometalate clusters has remained a problem due to the complexities of protonation states. The study uses mass spectrometry to determine the degree of protonation and number of heteroanions in polyoxometalates solutions. An overview of the study is provided.
