Abstract. Absolute integral cross sections (ICSs) for electron-impact excitation of the C ³Π_u, E ³Σ⁺_g and a'' ¹Σ⁺_g states of N₂ from the X ¹Σ⁺_g (v'' = 0) ground-state level are presented for electron-impact energies of 13, 15, 17.5, 20, 25, 30, 50 and 100 eV. ICSs are also presented for the individual vibrational levels of the C ³Π_u state (v' = 0, 1, 2, 3 and 4). The ICSs were derived from recent differential cross sections determined via energy-loss spectroscopy (Malone et al 2009 Phys. Rev. A 79 032704; Malone et al 2009 Phys. Rev. A 79 032705). The results are compared with existing measurements in the literature.
