✦ Synopsis


The coupled-cluster method in an open-shell version with non-Hen&an model interaction is applied for direct calculation of vertical ionization potentials of closed-shell molecular systems. The theory is illustrated by calculation of vertical ionization potentials of the water molecule. The calculated ionization potentials are in good agreement with experiment.
