Broad satellite peaks of varying intensities at binding energies above the main Fe 2p3/2 structure are present in the spectra for all high spin compounds. Variation in peak spacing and intensity occur for different ligands. All Fe(II) (high spin only as low spin Fe(II) does not exhibit multiplet splitting) and Fe(III) species can be fitted with Gupta and Sen multiplet structure. An analysis of satellite to main peak separation is also given. Multiplet FWHM, splittings and weightings are presented.
fitted the various iron oxide, hydroxide and halide peak shapes with a close approximation of the Gupta and Sen multiplet structure. used a series of multiplet peaks to curve fit oxidized iron sulfide (pyrrhotite) surfaces. McIntyre and Zetaruk’s paper is widely cited and is still an excellent starting point for qualitative iron oxide determination. Pratt et al. For the analysis of photoelectron spectra of relatively pure iron oxides, one can use peak shape and peak binding energy comparisons to standard compounds to derive oxide composition.
