Spectral intensity distribution shows that the electronic transition moment for NO (A2 X2II) transition varies significantly with inter-nuclear distance. The variation relationship of the electronic transition moment versus inter-nuclear distance is deduced with polyminal fit procedure. The spontaneous radiative coefficients for NO (A2X2II) transition from v' = 0,1 are obtained by combing this transition moment variation with the measurements of spontaneous radiative lifetime.展开更多
