Theoretical prediction for Coronene molecule modified with with four nitrogen atoms (here called as 4n-coronene). The files containing information about its geometry, how it was calculated and how the LCAO coefficients were taken are in the folder tests/4N-coronene. Her you can see the geometry of the molecule:
