We thank Luo Yi for sharing his calculations with us prior to publication, and also thank Jonas Weissenrieder and the staff at MAXlab. We acknowledge support by the European Community - Research Infrastructure Action under the FP6 ”Structuring the European Research Area” Programme (through the Integrated Infrastructure Initiative ”Integrating Activity on Synchrotron and Free Electron Laser Science”). KS acknowledges the Nanospectra network under grant number HPRN-CT-2002-00320 and the EPSRC for funding under grant GR/01880/01. This work, conducted as part of the award (”Functionalization of Carbon Nanotubes Encapsulating Novel Carbon-based Nanostructured Materials”) made under the European Heads of Research Councils and European Science Foundation EURYI Awards scheme, was supported by funds from the Participating Organizations of EURYI and EC-FP6.

N2 - We report on a study of the C 1s shake-up spectrum for bulk films of (C59N)2 and find a previously unobserved peak at 1.05 eV from the main line. This new peak can be attributed to the C 1s binding energy of sp2-like carbon atoms bound directly to nitrogen. We further analyse the spectrum by comparing it to a convolution of valence band and x-ray absorption spectra, which closely mimics the transitions possible in the presence of a core hole. The shake-up spectrum represents on-site excitons, and their onset is consistent with the optical gap of 1.4 eV.
