Photochemistry of hexachloroosmate(IV) in ethanol
The photochemistry of the Os IV Cl 6 2− complex in ethanol was studied by means of stationary photolysis, nanosecond laser flash photolysis, ultrafast pump-probe spectroscopy and quantum chemistry. The direction of the photochemical process was found to be wavelength-dependent. Irradiation in the re...
