How I know the possible contribution of each peak ? Like I have polyaniline and I have 3 peaks in O 1s what would be each peak is ( I did fitting but corrected but idk which is which )
fabulous , Will wait for few more video from your side. Such as how to find composition of element from high resolution peaks or survey peak . I will look forward for your post. Thank you for sharing your knowledge.
Hi Mark, Can you please add some information about C % or at% associated with these deconvoluted peaks in C 1s spectra ? Can we calculate the atomic % of Carbon involved with different C bonds using the Area %? or Is this calculated Area% same as Atomic % ?
Thank you for very helpful video. I am wondering why lattice oxygen peak should have one FWHM while the peaks, associated with the other species, another and constrained? What else defines peak FWHM beside core hole life time and instrumental broadening, which should be the same for different oxygen species?
Lattice oxygen has a formal charge and is well separated from the other contributions. The other peaks result from a variety of sources which cannot be clearly distinguished like ME-OH, C-O, C=O, COOH, defects etc. that are represented by just one peak.

Extremely helpful; Please make more videos for fitting of N and Pt if possible, please!
The software used here is called CasaXPS available at www.casaxps.com

Did you check the residuals of your fit? I feel that the value will be far greater than 1......
Hi Mark, thanks for the nice demonstration. May I ask if you have reference for the deficient xide peak?
See the references in this XPS Reference Pages Link - www.xpsfitting.com/2012/01/oxygen-1s-for-transition-metals.html
@@markbiesinger I appreciate your help!
Can you repeat the video with an explanation of the steps, because the picture is not correct
