Notes:
The He (I) photoelectron (PE.) spectra of bis (π-allyl)palladium (2a), bis (π-allyl)platinum (3a), bis (π-methallyl)palladium (2b) and bis (π-methallyl)-platinum (3b) have been recorded and compared with the PE. spectra of bis (π-allyl)nickel (1a) and bis (π-methallyl)nickel (1b). By use of the He (II) PE. spectra 2a, 2b and 3b and correlations between the PE. spectra of 1-3 it is possible to assign the first seven to eight transitions in the PE. spectra of 1-3. In contrast to previous assignments it is shown that the first band in the PE. spectrum of 1a corresponds to the ejection of an electron from 7au, a pure ligand orbital. The assignment proposed is supported by semiempirical calculations of the INDO-type by considering the relaxation effects explicitly using the ΔSCF and transition operator method.
