Scientific paper

The emission properties of the N2 c'4 1Σ u + - X 1Σ g + band system have been investigated in a joint experimental and coupled-channels theoretical study. Relative intensities of the c'4 1Σ u +(0) - X 1Σ g +(v i ) transitions, measured via electron-impact-induced emission spectroscopy, are combined with a coupled-channel Schrödinger equation (CSE) model of the N2 molecule, enabling determination of the diabatic electronic transition moment for the c'4 1Σ u + - X 1Σ g + system as a function of internuclear distance. The CSE rotational transition probabilities are further verified by comparison with a high-resolution experimental spectrum. Spontaneous transition probabilities of the c'4 1Σ u + - X 1Σ g + band system, required for modeling atmospheric emission, can now be calculated reliably.
