Pulsed photolysis cell – LASER-induced fluorescence

• Double-walled Pyrex enclosure (volume : 200cm3) with four optical accesses for laser diagnostic applications
• Temperature : 220 – 400 K et pression : 15 – 760 Torr
• Production of radicals by photolysis (excimer laser)
• Associated means of detection: laser-induced fluorescence (combination of YAG and dye laser)

Current application: kinetic studies of elementary gas-phase reactions involving the OH radical
