Abstract

The relative quantum yields of O(D-1) produced in the photolysis of ozone at 298 K between 300 and 328 nm have been measured directly by resonance-enhanced multiple photon ionisation of the fragment. Clear indications are seen of a tail in the quantum yield extending to the long-wavelength limit of the experiments. Comparisons with previous studies are made to assess the importance of the photolysis of vibrationallyexcited molecules and spin-forbidden dissociation at wavelengths beyond the 310 nm thermodynamic threshold for the formation of both atomicand molecular oxygen in their singlet states.
