N2 - Collisional mixing of (vib)rotational lines appearing in spectroscopic signatures of dense planetaryatmospheres and combustion environments is rigorously handled for the case of two linear collidersin terms of incomplete (non-Markovian) collisions related to off-energy-shell scattering amplitudes.Contrary to the standard impact-approximation approaches valid solely in band-centre regions, anew uniform broadband spectrum description is developed on the basis of a frequency-dependentrotational relaxation matrix which accurately accounts for the influence of the extra photon energywith respect to the molecular transitions. This matrix is built using a symmetric Liouville-spacemetric and obeys all known fundamental rules. Its direct calculation from refined potential-energysurfaces and promising modeling methods for forthcoming practical computations are outlined. Asimple preliminary test for N2–N2 isotropic Raman line widths argues in favor of considerable effectsof the internal perturber’s structure on modeled spectral characteristics.
