Primary photophysical and photochemical processes for hexachloroosmate(iv) in aqueous solution
The photoaquation of the Os IV Cl 6 2− complex was studied by means of stationary photolysis, nanosecond laser flash photolysis and ultrafast kinetic spectroscopy. The Os IV Cl 5 (OH) 2− complex was found to be the only reaction product. The quantum yield of photoaquation is rather low and wavelengt...
