Abstract : A flash photolysis apparatus has been designed and constructed. A maximum versatility in experimental arrangements has been incorporated within its design and initial special experiments and actinometry confirm expected results. The hydrofluoric acid-carbon dioxide gas-phase laser system has been chosen as the object of an intensive study of gas laser energy transfer mechanisms. Since the vibrationally and rotationally excited hydrofluoric acid molecule HF* can be produced photochemically by a variety of photoelimination processes and since hydrofluoric acid has a well resolved vibration-rotation spectrum (due to its small moment of inertia, I, and large rotational constant B), the hydrofluoric acid and carbon dioxide HF* + CO2 gas-phase laser system appears to be an excellent candidate for further examination by flash photolysis of energy transfer mechanisms in gas lasers.
