Multiply charged metal cluster anions.
Formation and stability patterns of silver dianionic and gold trianionic clusters are investigated with Penning-trap experiments and a shell-correction method including shape deformations. The theoretical predictions pertaining to the appearance sizes and electronic shell effects are in remarkable agreement with the experiments. Decay of the multiply anionic clusters occurs predominantly by ele...
متن کاملGas-phase activation of methane by ligated transition-metal cations.
Motivated by the search for ways of a more efficient usage of the large, unexploited resources of methane, recent progress in the gas-phase activation of methane by ligated transition-metal ions is discussed. Mass spectrometric experiments demonstrate that the ligands can crucially influence both reactivity and selectivity of transition-metal cations in bond-activation processes, and the most r...
متن کاملEnergy-dependent gas-phase fragmentation of fluorofullerene multiply charged anions (MCAs).
Long-lived di- and trianions have been formed from fluorofullerenes in the gas phase by electrospray ionization. Fragmentation of multiply charged anions has been induced by multiple low-energy collisions. Two complementary dissociation experiments have been conducted. Firstly, unequivocal connectivity has been established between the precursor ion and the first and second generation of its pro...
متن کاملPhotoelectron spectroscopy of multiply charged anions.
Multiply charged anions (MCAs) are common in condensed phases but are challenging to study in the gas phase. An experimental technique, coupling photoelectron spectroscopy (PES) with electrospray ionization (ESI), has been developed to investigate the properties of free MCAs in the gas phase. This article reviews the principles of this technique and some initial findings about the intrinsic pro...
متن کاملObservation of multiply charged silver-cluster anions
Singly charged silver-cluster anions are produced in a laser vaporization source and transferred into a Penning trap. After size selection the clusters are subjected to an electron bath in the trap, which results in the attachment of further electrons. The relative abundance of dianions or trianions as a function of the clusters’ size is analyzed by time-of-flight mass spectrometry. Silver-clus...
