Fast-atom bombardment mass spectrometry has been used to investigate the chemical behavior of Fe(III) and Mn(III) tetraarylporphyrins (TAP) in both the condensed and gas phases and to clarify the mechanisms responsible for the production of positive and negative ions. The differences in the behavior

The chemical behavior of Fe(III) and M(III) tetraarylporphorin (TAP) complexes with N-alkylimidazoles and other suitable ligands was studied by direct reaction in the fast-atom bombardment matrix and in the gas phase. The coordination reaction occurs at the metal center and yields molecular adducts
Complexation of aluminum ions {AI(III) in glycerol} with a-amino acids has been studied by FAB mass spectrometry. Twelve a-amino acids and cysteine methyl ester interact with different Al(II1)-containing ions and form several cluster ions such as [M+117]', [117={Al(LII)+glycerol-2H}]; [M+231]+, [231
