Abstract

The one-photon and sequential two-photon KrF* laser (248 nm) photodissociation of Cr(CO)6 and Mo(CO)6 were studied in a molecular beam using mass spectrometry to detect the photoproduct molecular ions. For Cr(CO)6, the major one-photon product, Cr(CO)4, undergoes secondary photodissociation to give predominantly Cr(CO)2. The photodissociation cross section of Cr(CO)4 is found to be 1.6 × higher than that of Cr(CO)6 at 248 nm. For Mo(CO)6, the major one-photon products, Mo(CO)5 and Mo(CO)4, undergo secondary photodissociation to give predominantly Mo(CO)3.
