Photodissociation of Cr(CO)6 induced by a KrF* excimer laser (248 nm) was examined under molecular beam conditions, using a quadrupole mass spectrometer with electron impact ionization (11-19 eV) to detect the products as their respective ions.The ions of all Cr(CO)x products (x=0-5) were produced upon photodissociation of Cr(CO)6 at laser fluences from 1 to 10 mJcm-2.The quantitative behaviour of the Cr(CO)+x product ion yields vs laser fluence as well as statistical rate calculations indicate that Cr(CO)4 is the major product formed upon single-photon dissociation of Cr(CO)6 under collisionless conditions at 248 nm.The additional Cr(CO)+x (x5mJcm-2, secondary photodissociation of Cr(CO)4 becomes important.Cr(CO)2 is assigned as the major photoproduct formed via secondary photodissociation of Cr(CO)4.

Medium effects on the photofragmentation of Cr(CO)6 are investigated to explain differences in the photochemistry occuring in gas and condensed phases.Results of two experiments are reported: (a) Collisional effects on the gas-phase photodissociation of Cr(CO)6 are investigated by multiphoton spectroscopic techniques. (b) Solution flash photolysis experiments on the picosecond time scale are reported.The primary photoproduct in condensed phase is Cr(CO)5, observed within 25 ps.
