For spin‑orbit split peaks (e.g., W4f, Ni2p, C1s), you can fix relationships between components:

Visually inspect the difference between your experimental data and the total fitting curve. A good fit will show purely random noise in the residual trace, without systematic waves or deviations.

Peak fitting can easily become subjective if not governed by rigorous scientific principles. Keep these rules in mind: A good fit will show purely random noise

XPS spectra consist of core-level peaks superimposed on a background caused by inelastic electron scattering. Accurate peak fitting requires modeling both this background and the specific peak shapes representing different chemical environments.

XPSPeak 4.1 is a legacy Windows-based software program designed for processing and fitting XPS data. It allows researchers to import ASCII data, subtract backgrounds, and fit curves using mixed Gaussian-Lorentzian functions. Key Features
