Photcelectron rneasurements on transition metal wrbonyls in the gas phase were made at various photon energΓ―es. Satellite peaks on the low kinetic energy side of the valrnce orbitals are observed and are attributed to shake up of the CO derived lerels. The variation of the Γ―ntensity of the shake up,

β¦ Synopsis
Saieflite pea& in the high energy photoelectron spectra of a number of transition m&x& are ropo*d, and their origin ts suggested DS arising from the poor description of the ground states of t&Se molecules in the Hartree-Fock limit.
In this work we describe measurements, obtained on an AEI ES100 photoelectron sprectrometer of the high energy photoelectron spectra of a number of transition metal carbonyls. Ali spectra were obtained on solid samples condensed from the vapour at liquid nitrogen temperature. In fig. 1 WE show the spectra in the region of the ionization of carbon and oxygen Is electrons for Cr(C0) . In addition to the peaks
