Ion/Molecule Reactions of Silver Cluster Cations with Crown Ethers in a Cylindrical Ion Trap

This is the authors' abstract. We don't add key points for this paper.

For observing gas-phase ion/molecule reactions of metal cluster cations, a cylindrical ion trap time-of-flight mass spectrometer was newly constructed. This apparatus consists of an external sputtering ion source, ion deceleration lens system, cylindrical ion trap and time-of-flight mass analyzer with four toroidal electric sectors. Using this apparatus, ion/molecule reactions of silver cluster cation, Ag 5 + , with crown ether, 12-crown-4 (12C4), were observed. The cluster-ligand complexes, [Ag 5 (12C4) n ] + ( n =1–3) and fragmentations of the cluster induced by adducts of crown ether molecules were also observed.
