Example of spectral energy correction applied to NEXAFS data collected several hours apart at the AS. (a) Spectra from poly{[N,N′-bis(2-octyldodecyl)-1,4,5,8-naphthalenedicarboximide-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)} [P(NDI2OD-T2)] after normalizations. (b) Uncorrected reference spectra of HOPG taken concurrently with the spectra in (a). (c) The same spectra of P(NDI2OD-T2) with the energy scale of each corrected by the location of the exciton peak at 291.65 eV (Watts & Ade, 2008BB24) in HOPG after which normalizations are performed. (d) The corrected HOPG reference spectra with the characteristic exciton absorption peak corrected to 291.65 eV.
