Abstrakt: Quantitative spectroscopic observations of the N2 first positive band system (N2(B 3Πg-A 3Σu+))/electron in a recombining N2H+ flowing-afterglow plasma indicate that a substantial fraction of the product N2 molecules are formed in one or more of the low-lying triplet states, B 3Πg, A 3Σu+, and W 3Δu. The total measured N2(B-A) emission intensity from N2(B,v>=1) is equivalent to a yield of (19±8)%. The effect of rapid collision-induced transitions between states of the triplet manifold is discussed. © 2004 American Institute of Physics. [ABSTRACT FROM AUTHOR]
