On the correlation between photoelectron energy and bending excitation in molecular photoionization

Abstract

We report on excitation of the bending vibration following 3σu−1 photoionization of CO2. Dispersed fluorescence is used to determine the v+=(0,1,0)/v+=(0,0,0) ratio over the range 18⩽hνexc⩽190 eV. The results demonstrate that the bending excitation varies over this wide range, and is influenced by the photoelectron.
