โฆ Synopsis
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 21.15 _' 0.15 and 34.2 * 0.2 eV respectively. Recent experiments have shown that the (e, 2e) technique (electron-impact ionkation with the two
