Abstract
Interpretations of mass spectra usually depend on explanations of the molecular structure by determination of the fragmentation ions structures. Therefore, identification of fragmentation ions formulas is an initial step of such investigations. It seems that multi-isotopic modelling of all ions proposed in fragmentation data should lead to the theoretical mass spectrum. Good adjustment of experimental and predicted spectra proves the validity of the fragmentation table, whose contents are recognised as fragmentation hypothesis. This means that multi-isotopic modelling is a helpful tool for verification of proposed fragmentation data. Applications of the method are presented for 1,1′,2,2′,3,3′-hexachloro-ferrocene, C10H4Cl6Fe, and bis(dibutyldithiophosphate)-zinc(II), [(C4H9O)2PS2]2Zn.
