Abstract
Picosecond absorption spectroscopy has been used to examine the photodissociation of Cr(CO)6 in a variety of solvents. In alkane solutions, photodissociation results in loss of a CO followed by solvent coordination within 1 ps of excitation. In the series of n-alcohols, n-nitriles, and n-alkyl bromides, rapid dissociation is also observed. However, in these solvents, the time-resolved spectra indicate that following photolysis, primary intermediates are formed which are comprised of a distribution of complexes involving the coordination of different moieties of the solvent molecules to the vacant site on the metal.
