Method of calculation of synthetic emission spectra of triplet states of molecular nitrogen in apolars

A method for calculating synthetic emission spectra of systems of triplet levels of molecular nitrogen is presented: Vegard- VK N2(A^3 Σ_u^+→X^1 Σ_g^+), the first positive system 1PG N2(〖 B〗^3 Π_g→A^3 Σ_u^+), the second positive system 2PG N2(C^3 Π_u→B^3 Π_g). The individual structures of the corresponding molecules are taken into account. The populations of the vibrational levels of the triplet states are calculated taking into account the energy transfer between triplet levels in collisional reactions and the intramolecular redistribution of energy. Examples of calculation of synthetic spectra are presented.
