For C2N2 the region between 60 and 80 nm is dominated by a broad ionization continuum upon which a very weak vibrational structure has been superimposed. Between 80 and 105 nm, there appear to be at least four overlapping Rydberg series which converge to adiabatic ionization potentials obtained from photoelectron spectroscopy.
