Autoionisation of superexcited states in N-2 to the N2+B state
2003 (English)In: Chemical Physics Letters, ISSN 0009-2614, E-ISSN 1873-4448, Vol. 372, no 02-jan, 139-146 p.Article in journal (Refereed) Published
Vibrationally resolved N-2(+) (B-X) (1-2) and (0-1) emission bands were recorded after photoexcitation of N-2 in the 20-46 eV energy range. The branching ratio between these transitions reveals strong non-Franck-Condon effects. Ab initio calculations using a configuration interaction method based on Kohn-Sham orbitals indicate that the autoionisation of certain superexcited states is responsible for some structures present in the branching ratio curve.
