The research included the use of the atom radial decomposition functions \(RDF\) and infrared spectroscopy. The results of RDF analysis and infrared absorptive spectroscopy have revealed the existence of oxygen\-silicone tetrahedra. Moreover, the most probable nitrogen location in oxide\-nitrogen glass has been confirmed."]
