Abstract:

Newly measured natural lifetimes for vibrational levels 1-8 and 10 of the doublet Piu state of N2 have been analyzed by a weighted, non-linear, least squares technique to extract the absolute transition moment and its dependence on internuclear distance. Both are considerably different from previous results and lead to different transition probabilities and oscillator strengths. Transition probabilities for both v 0 and 9 are obtained by interpolation of the electronic portion of the band strength and result in predicted values for the lifetimes of the v 0 and 9 levels.
