Successive ionization energies are not
represented in the experimental photoelectron spectra. It’s
important to realize that PES simply shows the energies required to
photoionize ONE electron from a neutral atom. In the case of the
nitrogen PES spectrum you examined in section, the one electron
photoionized can be from the 1s, 2s or 2p subshell in its ground
state.
In contrast, successive
ionization energies correspond to the removal of
more than one electron from a given atom. These
electrons are...
