# XPS for different oxidation states

1. ### sum555

Dear All,

for different oxidation states of the same element in X-ray photoelectron spectroscopy measurements, should the full width half maximum (FWHM) value be the same for all? Is this a parameter to fix in this case for the fitting?

I am studying an amorphous transition metal oxide thin film on glass.

Thanks a lot!!
