Abstract

Symmetry-resolved ion-yield spectroscopy of vibrationally excited N2 O in the vicinity of the O 1s ionization threshold has been carried out using an angle-resolved ion detection technique. The spectral intensity of the O 1sans' Rydberg series, which has '* valence character, is significantly reduced by the excitation of the bending vibration in the electronic ground state. Using an ab initio analysis of the electronic part of the second moment â r2 â, this suppression is interpreted as being due to a decrease in the mixing of the valence character in the ns' Rydberg states with decreasing bond angle.
