Transition from atomic to molecular adsorption of oxygen on tungsten monomer anion.
Using vibrationally resolved ultraviolet photoelectron spectroscopy, we studied oxygen adsorption on W monomer anions. Three oxygen atoms are atomically bound in a WO3- compound, whereas in WO4- the fourth oxygen atom is attached to the oxygen, forming a di-oxygen species, implying that atom to molecule transition of O2 takes place when the number of oxygen atoms attached to a W monomer anion e...

متن کاملLack of thermodynamic equilibrium in conjugated organic molecular thin films
We show that the observation by photoemission spectroscopy of a finite density of occupied states at the Fermi-level on a film of a conjugated organic material ~para-sexiphenyl! in which alkali metal atoms have been intercalated does not necessarily imply metallicity nor the presence of negative polarons ~radical anions!. The combination of ultraviolet photoemission spectroscopy and Kelvin prob...
متن کاملElectronic Level Structure of Group Iii Heavy Element Clusters Studied by Photoelectron Spectroscopy
UV-photoelectrons of mass-defined indium and thallium cluster anions have been analyzed at a detachment energy of 3.68eV in the size range n = 2-20. The photoelectron threshold energies are in rough agreement with the values predicted by the metal droplet model. A number of low-lying excited states of the neutral-clusters are detected. The high atomic s-orbital binding energies appear to induce...
متن کاملStructure Matters: Combining X-Ray Scattering and Ultraviolet Photoelectron Spectroscopy for Studying Organic Thin Films
In this chapter the relationship between organic film structure and ultraviolet photoelectron spectroscopy (UPS) data is discussed. As a useful method for obtaining detailed structural data we first summarize shortly the advantages of X-ray scattering. Here, of course we cannot include the full body of literature on interface-sensitive X-ray scattering but rather refer to general references. By...
