代表分峰拟合的时候，将Fe 2p的强谱峰分成了浅红色的Fe (Ⅱ)峰和浅绿色的Satellite峰。 Satellite的英文意思是卫星，即浅绿色的峰代表的是 卫星峰，也就是小的伴峰的意思。

可以使用 Fe2p 的卫星峰区分 Fe 的各种氧化态。 主峰与卫星峰的相对结合能和强度比因化合物而异，例如，相较于 FeO，FeCl 2 具有非常强的卫星峰。

Feb 15, 2008 · The peak positions and peak shape parameters of Fe 3p for Fe 2+ and Fe 3+ were derived from the Fe 3p XPS spectra of the standard samples of 2FeO·SiO 2 and Fe 2 O 3, respectively. Using these parameters, the Fe 3p peaks of Fe 3 O 4 and Fe 1−y O are analysed.

Fe2p region has significantly split spin-orbit components (Δ metal =13.1eV). Fe2p peaks have asymmetric shape for metal. A well resolved Fe2p 3/2 spectrum for metal shows multiplet …

The high-resolution Fe 2p spectrum (Figure 3b) displayed widened Fe 2p3/2 and Fe 2p1/2 peaks, trivalent iron (Fe 3+ ) located at ~712.67 and ~724.45 eV, respectively, and another peak at...

Ferrous (Fe2+) and ferric (Fe3+) compounds were investigated by XPS to determine the usefulness of calculated multiplet peaks to fit high-resolution iron 2p3/2 spectra from high-spin compounds. The multiplets were found to fit most spectra well, particularly when contributions attributed to surface peaks and shake-up satellites were included.

Aug 22, 2024 · Examination of the literature reveals that one of the most widely used approaches to data reduction when processing Fe 2p 3/2 spectra involves using symmetric two- or three-component peak fitting with each peak effectively acting to capture a single chemical species (chemistry fit) in the complex spectra.

Jun 19, 2022 · Overlays of Fe (2p) Spectra for Fe Native Oxide and α-Fe2O3 (Hematite) Caution: BEs from Grounded Native Oxides can be Misleading if Flood Gun is ON

Apr 1, 2013 · We start the discussion of the 2p XAS spectra of iron systems with an isolated iron atom. This allows us to explain some of the fundamental issues concerning L edges, in particular the importance of intra-atomic interactions such as the 3d3d interactions, the 2p3d interactions and the 2p and 3d spin–orbit coupling.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.
