Resonance-enhanced multiphoton ionization coupled with time-of-flight product imaging has been used to study the O3(X 1A1)+hν→O(2p 3PJ)+O2(X 3Σg−) product channel in the UV (ultraviolet) photodissociation of ozone at photolysis wavelengths of 226, 230, 233, 234, 240, and 266 nm. These imaging experiments, together with a measurement of the branching ratio into the different spin orbit states of the O atom, allowed the determination of the yields of the O2 product in vibrational states greater than or equal to 26 as a function of wavelength. It was found that at 226, 230, 233, 234, and 240 nm, the yield was 11.8±1.9%, 11.5±1.2%, 8.2±2.0%, 4.7±1.8%, and 0.6±0.1%, respectively. © 2000 American Institute of Physics.
