N2 - We have measured the multiphoton ionization spectra of Cr(CO)6, Cr(CO)3C6H6, Cr(CO)3C6H5Cl, and Cr(CO)3C6H5CH3 in the region 355-365 nm. We have identified previously unassigned features, in particular, an even-parity 7S3 Rydberg series of neutral bare chromium atoms. From the assignment we have obtained an improved value for the ionization potential, the quantum defect and evidence for electron correlation and nuclear screening effects in the bare chromium atom. Coupled with assignments of other nearby spectral features we have also obtained the first evidence of intramolecular vibrational redistribution (IVR) competing with multiphoton up-pumping of organometallic molecules.
