Abstract
The gas-phase reactions with propargyl alcohol (PPA) of all the singly char ged ions of the first-row transition metals, generated by laser ablation in an external ion source, were studied by Fourier transform ion cyclotron re sonance mass spectrometry (FT-ICRMS.). The reactivities of the metal ions c hange irregularly across the periodic table, and the reactivity of each ion is a function of its electronic configuration and corresponding metal-oxyg en (M-O) bond energies. The 10 metal ions were classified into three catego ries according to their reactivities: Sc+, Ti+ and V+ are the most reactive ions which react with PPA to give many kinds of oxygen-rich products due t o stronger M-O bonds; Fe+, Co+ and Ni+ are less reactive; Cr+, Mn+, Cu+ and Zn+ are the most unreactive ions, due to the half and completely occupied valence electronic configurations. The order of reactivity is Ti+ > V+ > Sc + > Co+ > Fe+ approximate to Ni+ > Zn+ > Cr+ approximate to Mn+ approximate to Cu+. Copyright (C) 2001 John Wiley & Sons, Ltd.
