Thus it offerds both informations of molecular structures and gas phase molecular-ion reactions. This paper summarizes the results on hottopics: (1)comparison of EI and FAB mass spectrometry and its correlation to clusteconversion for MoFe3S4L5 (L= S2CNC4H8) cuban-type clusters F (2) the recombinatiolreaction of fragment species of some metal complexes and clusters in mass spectrometry.Keywords: metal (complex) cluster compound, mass spectrometry, recombination reaction.
