Emission spectroscopy is used to investigate effect of gas composition on macro and microscopic parameters (radiative spectral distribution, translational temperature, rotational temperature, electronically – vibrationally – rotational energy distribution functions in the electronic excited С3Пu and В3Пg - states of the nitrogen molecules, and as well as B2Σu+ - state of the nitrogen ion molecules) of DC glow discharge (pressure of 7.6 Torr, discharge current of 70 mA and 90 mA, percentages of N2 4.5% 35% and He 95.5% 64.5%) and the strongly inhomogeneous microwave discharge generated near the end of the electrode antenna (frequency of 2.45 GHz, pressure 4.8 Torr, incident microwave power of 108 W, percentages of N2 1.6% 50% and He 98.4% 50%). New approach of processing and modeling of plasma emission spectra was developed for reconstruction of nonequilibrium energy distributions of excited hydrogen, helium atoms and nitrogen molecules in the case of spectral overlapping of the atomic lines and molecular bands.
