Resonant Auger spectra following O 1s-(1)Pi(u) excitation of metastable oxygen a (1)Delta(g) molecules have been measured at high resolution under resonant Raman conditions. By selectively monitoring various decay channels, the singlet manifold excitation spectrum has been separated from the dominating triplet excitation.

Abstract
Resonant Auger spectra following O 1s-(1)Pi(u) excitation of metastable oxygen a (1)Delta(g) molecules have been measured at high resolution under resonant Raman conditions. By selectively monitoring various decay channels, the singlet manifold excitation spectrum has been separated from the dominating triplet excitation. The decay spectra have been analyzed using the lifetime-vibrational-interference model to give the spectroscopic parameters of the 1s excited (1)Pi(u) state of O-2. Singlet and triplet manifold Auger decay rates are also compared.File in questo prodotto:
