The first ionization energies of a number of (CO) 2 M(β‐diketonate) complexes (M = Rh, Ir) were measured by electron impact. The hypothesis of a first ionization from a molecular orbital with a significant participation of the central metal atomic orbital is proposed for these complexes. The results obtained previously with other metal β‐diketonates are shown to be consistent with the proposed rationalisation.
