Absorption oscillator strengths, calculated with the molecular quantum defect orbital method, for the […. ] bands of molecular nitrogen are reported. The Rydberg–valence interaction between states of [..] symmetry has been treated through an interaction matrix that includes vibrational coupling. Due to the homogeneous interaction, the intensity distribution of the bands within each progression deviates from the Franck–Condon predictions. The present results for vibronic transitions from the […] ground state agree rather well with reported high-resolution measurements. As far as we know, f-values for bands originating from v'' > 0 vibrational levels of the electronic ground state are reported here for the first time. These data may be useful in the interpretation of the extreme ultraviolet spectra from Earth's and Titan's atmospheres, in which several bands of the […] and […] progressions have been identified.
