Highly excited states of gerade symmetry in molecular nitrogen

Highly excited states of gerade symmetry in molecular nitrogen have been investigated in a resonance-enhanced XUV+Vis (extreme ultraviolet+visible) transition scheme. Nineteen bands have been observed, of which only four involve known states [k 1Πg (v=1), x 1Σg− (v=2), and y 1Πg (v=1,2)], albeit in...

Zusammenfassung:Highly excited states of gerade symmetry in molecular nitrogen have been investigated in a resonance-enhanced XUV+Vis (extreme ultraviolet+visible) transition scheme. Nineteen bands have been observed, of which only four involve known states [k 1Πg (v=1), x 1Σg− (v=2), and y 1Πg (v=1,2)], albeit in new systems. Three of the newly observed states have been assigned as y 1Πg (v=3) and k 1Πg (v=2,3). Level energies are determined with an accuracy of ≈0.20 cm−1.
