The standard rate constants for the redox reaction Eu(III) + e , Eu(II) were calculated from cyclic voltammetry dataE. The sluggish kinetics of this reaction is discussed in terms

FIGURE 2 Photoelectron spectra of Ag 2 O − 2 using a single femtosecond pulse with a photon energy of 3.1 eV (lower trace), two femtosecond pulses with 3.1 eV and 1.55 eV

The spectrum at 7-ps delay exhibits additional peaks (marked X 1 –X 4 ), which we tentatively assign to transitions from an excited state of the anion AuO − 2 into the ground

It is important to note that discrimination between direct and thermal desorption is straight forward in TRPES experiments: in a direct process the excited state feature is expected
