Fitting the oxygen O1s core level
There is a few choices to make on the fitting of the O1s level. The level is an s-orbital and thus gives rise to a peak that is symmetric so any non-symmetric appearance must be caused several states of oxygen. The question is then to which states of oxygen they should be attributed. Below are shown the spectra of levels 0 (surface), 11 and 20.
