The Valence Hole Spectrum of CO

Quasi-Particle Properties of Hole Levels in Molecules 

The JSCF static relaxation shift for the 5 a level was obtained from Bagus and Vii-nikka112), A l = 1.8 eV, and we have assumed it to be valid for the other outer valence hole levels as well. The 3 a A SCF level shift has been estimated from inspection of the results of Schirmer et al.109) to be 2.5-3.0 eV.
