Figure 3
Oxygen XANES spectra of PMMA, showing the dependence on the dose at (a) room temperature and (b) liquid-nitrogen temperature. The spectra show the decrease of the C=O bond density with increasing dose. The C=O bond peaks were fitted using Gaussians. Also shown are the average values, denoted by upper and lower plateaus, used to determine the oxygen mass loss.
