A combination of XPS and solid-state N NMR have been used to characterize the nitrogen forms in a variety of different carbonaceous samples having high natural nitrogen abundance. It is currently difficult to unequivocally interpret and quantify individual 15 N NMR and XPS spectra. The advantages of
