Photoelectron Spectroscopy of Atomic Clusters - Laser Vaporization Source
This experimental facility couples an electrospray ionization source to a magnetic-bottle time-of-flight photoelectron spectrometer. It has been developed to investigate multiply charged anions and solution phase species in the gas phase. An electrospray ion source, in which a solution sample containing the anions is sprayed through a syringe needle under negative bias, is designed and developed to produce multiply charged anions. Ion-trap-time-of-flight mass spectrometry is used to analyze the formed anions. Size- and charge-selected photodetachment photoelectron spectroscopy is used to obtain information about the stability and electronic structure of the anions and their microscopic solvation. A wide range of anionic species, important in organic, inorganic, and biochemistry, as well as in solid materials and catalysis, are being investigated.
