✦ Synopsis

U + ) and polycyclic aromatic hydrocarbons (e.g. pyrene (Py)) and their aza-analogs (e.g. 9-azaphenanthrene (Ap)) as neutral ligands in a laser desorption/ionization Fourier-transform mass spectrometry experiment are measured immediately and over some time period after each laser shot. If both types of ligands or two or more types of metal ions are present their competition in the formation of compounds with mixed ligands for different metals is observed. The reactions of a Fe + , Cr + and Ni + mixture with a Py and Ap mixture are given as examples. The relative half-lives for some of the observed ionic species were determined assuming steady state concentration of the neutral reactants during the experiment.

The laser ablation with prompt reaction and detection method was employed to provide a survey of some gasphase reactions of actinide (M = U, Np, Pu and Am) and lanthanide (M = Tb and Tm) ions, M Y and MO 1,2 Y , with alcohols, thiols and ethers. Particular attention was given the changing behavior i

A method is described in which the coordination number in metal complexes can be determined using ion-molecule reactions in a quadrupole ion trap mass spectrometer. Complexes of Ðrst-row transition metals in the + 2 oxidation state, including manganese through zinc, are electrosprayed, isolated in t
