A direct measurement of the O(D-1) quantum yields from the photodissociation of ozone between 300 and 328 nm
The relative quantum yields of O(1D) 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 t...

| Samenvatting: | The relative quantum yields of O(1D) 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 vibrationally excited molecules and spin-forbidden dissociation at wavelengths beyond the 310 nm thermodynamic threshold for the formation of both atomic and molecular oxygen in their singlet states. |
