CO internal excitation in the photodissociation of Cr(CO)6 at 278 nm

Abstract

Time-resolved infrared diode laser spectroscopy has been used to probe CO internal excitation in the photodissociation of Cr(CO)6 at 278 nm. At the high fluence level of these experiments, CO state distributions are not consistent with a statistical model of single-photon absorption. A simple Franck—Condon treatment, assuming multiphoton absorption into a dissociative continuum, qualitatively describes the observed CO vibrational distribution.
