Figure 2
NEXAFS spectrum of a polyimide foil taken with the STXM at U41 at BESSY II. The optical density is plotted as a function of energy. Identification of functional groups is possible: the π* resonances of the C=C and C=O groups are followed by the σ* resonances of the C—N, C=C and C=O groups.
