Webinar on Curve Fitting in XPS: Good Practices and Tools for Avoiding Mistakes

Curve fitting has been widely used for extracting chemical information from the overlapping features in high-resolution XPS spectra. It is challenging to develop a chemically and physically meaningful approach to curve fitting. In this webinar we discuss the theory behind XPS curve fitting, demonstrate practical approaches for analyzing XPS core regions, and what common mistakes should be avoided when curve fitting. Topics addressed will include choosing an appropriate background, handling overlapping peaks, fitting transition metal spectra, appropriately constraining spin-orbit split peak ratios and energy separation, and others.

very helpful webinar thank you

[@vinayjoru4792]

Thanks for providing more threads to work XPS data analysis. Can anyone explain what is the 'Si' peak obtained at 99.66 eV in the video at 35.21in spin-orbit coupling examples?

For Multipak, anyone know when we need to use the "Shft" feature to shift the spectrum?
Like the example in 35:54 is shifted, indicated by (Shft) in red colour beside the sample description, but those in 20:07 etc aren't

[@prasadmattipally]

Which software using to curve fit madam. Let me know i also to use

[@ramversingh7867]

Multipak software

Hello .
Why xps not detect H and He ?

[@abiodunaderibigbe4853]

H and He only have valence and not core electrons.

34:07 I think you should not ignore spin orbit splitting of the oxide. In the shown example you can see that the fit is not good. Its just an unnecessary simplification.
