Abstract:The emission spectra of OH(A2Σ→X2Π, O—O), O(3p5P→3s5S02) and Hα(3P→2S) produced by the positive pulsed corona discharge of N2 and H2O mixture in a needle-plate reactor have been successfully recorded against a severe electromagnetic interference coming from the pulsed corona discharge at one atmosphere. The relative populations and the vibrational temperature of N2(C, v′) were determined. The emission intensity of OH(A2Σ→X2Π, 0—0) is obtained through the simulation of the emission spectra of the Δv=+1 vibration transition band of N2(C3Πu→B3Πg). Relative populations of OH(A2Σ), O(3p5P) and Hα(3P) have been obtained by the emission intensity of OH(A2Σ→X2Π, 0—0), O(3p5P→3s5S02) and Hα(3P→2S) and Einstein’s transition probability. The effects of discharge voltage and pulse repetition rate and oxygen flow on the relative populations of OH(A2Σ), O(3p5P) and Hα(3P) are investigated.
