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 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...
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 کاملPhotoelectron angular distribution and molecular structure in multiply charged anions.
Photoelectrons emitted from multiply charged anions (MCAs) carry information of the intramolecular Coulomb repulsion (ICR), which is dependent on molecular structures. Using photoelectron imaging, we observed the effects of ICR on photoelectron angular distributions (PAD) of the three isomers of benzene dicarboxylate dianions C6H4(CO2)2(2-) (o-, m- and p-BDC(2-)). Photoelectrons were observed t...
متن کاملSmall Multiply Charged Anions as Building Blocks in Chemistry
Chemists view most if not all ionic crystals as composed of autonomously stable negative and positive ions. These building block ions can be singly or multiply charged (e.g., NaCl(s) consists of Na+ and Clions, and MgSO4(s) contains Mg2+ and SO4 ions), but they are expected to be stable to the extent that they can be characterized in the laboratory. Dividing crystals, melts, and ionic molecules...
