AN X-RAY PHOTOELECTRON SPECTROSCOPIC STUDY OF ARENE CHROMIUM TRICARBONYL COMPLEXES AT 170 K

Core and valence region XPS spectra of methyl-substituted benzene chro mium tricarbonyl complexes have been measured at low (170 K) temperatu re. The core levels were found to be unchanged by the addition of the electron-donating groups on the ring, whilst the shifts in the valence bands have been related to the bonding mechanisms within these compou nds.
