ESI–IT–MS n and DFT calculation for electron affinities of bimetallic oxovanadium complexes

Abstract

The MS n spectra of three bimetallic oxovanadium complexes were obtained using an ion trap. The fragmentation pathways were elucidated. Common features and major differences between ESI-QTOF-MS/MS and ESI-IT-MS n spectra were compared. Electron affinities of several radical molecular anions were calculated by DFT and these could be used as an indicator of the ions' stability.
