(a) Corrected TEY signal from P(NDI2OD-T2) at different incident angles, showing the artificially increased intensity of shallower angles. (b) The same set of data step-scaled to 0 at the pre-edge (280 eV) and 1 at the post-edge (320 eV). Inset is a closer view of the π* resonances from around 284–286 eV. (c) The bare-atom spectra (Henke et al., 1993) calculated from the molecular structure (inset) with overlaid measured NEXAFS spectra, which have been scaled to match the bare-atom mass absorption spectra at the edges of the data range. (d) The same spectra from (a), scaled to the bare atom mass absorption, and corrected to the imaginary part of the index of refraction using a nominal density of 1 g cm−3. Inset is a closer look at the π* resonances from around 284–286 eV. |
