The report describes a model which is suitable for rapid calculation of the population distribution among energy levels in radiating species and of radiation in selected spectral intervals as well as band profiles for vibration-rotation bands. In calculating the population distribution among energy levels, the steady-state assumption was made for a system in which five types of transitions occur the formation of the radiating molecule in each energy level by reactions, the loss from each energy level by reactions and the formation of loss of molecules in each energy level by 1 collisional excitation, 2 collisional de-excitation or 3 radiative decay of molecules in that or other energy levels. The density of the radiating molecules in each energy level is given in a canonical form with associated recursion relations which permit rapid evaluation of the density. Illustrative calculations are provided for nitric oxide as the radiating molecule. Modified author abstract
