Abstract: We have determined the on-site molecular Coulomb interaction energy U of a (C59 N)2 bulk film and find values ranging from 1.10±0.10 eV for the highest occupied molecular orbital to 1.35±0.10 eV for the deeper lying orbitals, comparable to values found in C60. The on-site Coulomb interaction between a carbon core hole and valence electrons, Uc, is, however, substantially lower than in C60 at 1.35±0.07 eV. Resonant photoemission (RESPES) results show a weakened participator decay channel, especially around the N 1s threshold, where resonance of the highest occupied molecular orbital shoulder is absent. Near-edge x-ray absorption fine structure and constant initial state measurements, taken in parallel with the RESPES data, indicate, however, that matrix element effects cannot be ruled out. © 2007 American Institute of Physics.
