Abstract The ultravioletphotoelectronspectra of Cr(CO) 5 (4-RPyr) have been measured, and the IP's observed below 12 eV are discussed. Bands found in the region 7-8 eV are assigned to ionization from the chromium d orbitals. The IP values are shown to increase with the increasing electron acceptor nature of the ring substituents. The remaining bands below 12 eV are assigned to the pyridine orbitals
