Photoionization (PI) spectrum of the N2 molecule is modelled using a first-principles approach combining the multichannel quantum defect theory and electron scattering calculations performed using the UK R-matrix codes.  The PI spectra were determined starting from the lowest and several excited vibrational levels of N2 in the ground electronic state of N2. Excited electronic states and vibrational motion of the N2+ ion are accounted for.  The spectrum obtained for the lowest vibrational level of \nn was compared to available experimental data. Major resonances in the obtained spectrum were characterized using the quantum defect technique.
