WebOct 7, 2024 · The choice of the particular electronic structure method and package depends on available computer resources and on the size and complexity of the cluster system (e.g. pure metal cluster vs. nanoalloy, presence or absence of ligands and/or supporting surface, importance of magnetism). GO algorithms can be distinguished in a number of ways [ 10 ]. WebThe electronic and geomctric structure of free metal cluster anions is studied by photodetachment. The cluster anions are produced in a PACIS (Pulsed Arc Cluster Ion Source). From mass separated… 5 PDF Photoelectron spectroscopy of silver and palladium cluster anions.
