Our recent findings of suitable conditions for observation of the unperturbed HIR system (Annusova et al Contrib. Plasma Phys. 2017) gave us the opportunity to develop and test a numerical representation of this complex system composed of 75 branches. Commonly, the HIR covers a part of the near infrared spectra (690-850 nm) with its bands mixed with the N-2 first positive system (IPS), which hinders applications of these systems for optical metrology of the discharge. In this work, we present a complex ro-vibrational model of the IPS and HIR systems, which allowed us to untangle their spectra and retrieve the rotational temperature and vibrational populations of the systems for the first time. The latter was achieved by coupling the PGHOPHER simulation package with molecular constants obtained from high-resolution experiments. To test the model, the results and precision were compared to the retrievals based on the models of the NO gamma and N-2 second positive systems using the LIFBASE and SPECAIR programs, respectively.
