In this study, the photodissociation of H2O2 dilute in argon at 193 nm has been investigated using near infrared frequency modulation laser absorption spectroscopy on selected rotational lines of the OH vibrational overtone bands between 6500 and 7100 cm-1 to detect the OH and HO2 radical products with the same laser. Sequential OH and HO2 time-dependent profiles have been measured at room temperature and total pressures ranging from 3 to 56 Torr. Kinetic analysis gives the product distribution following H2O2 photolysis of (82±1) % OH and (18±1)% HO2 under the present conditions, in excellent agreement with previously reported measurements.
