摘要：

The vertical ionization potentials of model hydrogen chains have been calculated, in the framework of STO-3G and 4-31G bases, at the second-order level of the many-body Green's function theory. Compared to the second-order many-body perturbation theory, this approach provides a qualitative description of trends observed with orbital relaxation, pair removal, and pair relaxation effects when studying oligomeric systems of increasing size with varying bond length.
