| Popis: |
The intensity distribution in the rotational structure of the electronic band B 2 Σ + g → X 2 Σ + g of N + 2 (0,0) was measured by high-resolution Fourier transform spectrometry. This spectral information enabled estimates of the rotational temperatures in atmospheric-pressure argon-nitrogen inductively coupled plasmas (Ar-N 2 ICPs). These rotational temperatures were compared to the excitation and the Doppler temperatures of Ar ICP and Ar-N 2 ICPs having from 0 to 100% nitrogen in the outer gas flow. The rotational temperature of the mixed-gas plasmas ranged from 5500 to 10000 K, depending on the percentage of nitrogen in the outer gas flow, compared to 7800 K for the Ar ICP. The lowest and the highest rotational temperatures were obtained when the outer gas flow contained 100% and 17% nitrogen, respectively. |
