Investigation of the rovibrational levels of the B3Πg state of 14N2 molecule above the dissociation limit N(4S) + N(4S) by Fourier transform spectrometry

Rotational analyses of vibrational levels of the B3Πg state, located above the dissociation threshold N(4S) + N(4S) were performed from a high-resolution emission spectrum recorded by Fourier transform spectrometry. Strong intensity perturbations were observed in the B3Πg vibrational levels ν′ = 13, 14, and 15.
