We have measured the vibrationally resolved partial cross sections and asymmetry parameters for C K-shell photoionization of the CO2 molecule in the Σu shape resonance region above the C K-shell ionization threshold. The positions of both the maxima of and the minima of move towards the C K-shell threshold with increasing symmetric stretching vibrational excitation v′1 in the C 1s single-hole state. Calculations employing the relaxed-core Hartree-Fock approach reproduce the observed vibrational effects.
