Zusammenfassung

Photoelectron spectra of mass-selected negatively charged bare Nin - and Ptn - clusters are compared with the spectra of Nin(CO)m- and Ptn(CO)m - clusters. The spectra indicate that saturation with CO is caused by the formation of an electronic closed shell and not due to steric hindrance as on a surface, and that the strength of the π backdonation of the CO chemisorption bond to a small particle is stronger than to a surface. The antibonding metal (dz2-5σ) orbital resulting from the interaction of the CO 5σ with the metal dz2 orbitals is directly observed for Ni1(CO)3 -.
