The angular variation of the binding energy spectrum in an electron-electron coincidence experiment indicates that the third and fourth ionization potentials of formaldehyde are due to the Sal and lb2 orbitals respectively. The vertical ionization potentials of the 4al and 5x1 orbihk are found to be

โฆ Synopsis
The Hartrce-i:ock calculations and the SCF Xa scattered-wave method using overlapping spheres predict B different ordering of the ionization potentials of formaldehyde.
To clarify the problem a Green's function approach includiq many-body effects is used. The caiculatcd ionization potentiais as well as th: vibrational structure of the bands asrce well with experiment. We conclude the Hartrec-Fock assignment to bc the correct one.
