| Abstract: | The excitation mechanism for O2 Herzberg Bands as given by Young and Black (1966) is examined. It is found that O2 Herzberg Bands are heavily quenched by N atoms, while (0,0) and (0,1) Atmospheric Bands are quenched mainly by CO, NO, O2 and N2, NO, O2 respectively. The emission of Herzberg Bands is found to arise from two layers centred at 80 and 100 km. The rate coefficients of a number of quenching reactions involving atmospheric gases are obtained theoretically. |
