Abstract

The site-specific 1s core-level photoionization of N2O molecules has been studied experimentally and theoretically at a time-dependent density functional level. The photoelectron angular distributions have been measured from the oriented molecules. The effects of site of ionization, of energy dependence and of configurations of molecular axis and polarization vector, have been discussed. The presence of two shape resonances is reflected in the particular behaviours observed in the photoelectron angular distribution, while their nature has been assessed in terms of the calculated photoelectron wavefunction. Comparison with isoelectronic CO2 molecules suggests that symmetry lowering does not play an important role, except for the resonant energy region.
