O(1S) yield from O3 photodissociation at 1700–2400 Å

Abstract
The O(1S) yield from O3 photodissociation is measured in the 1700–2400 Å region using synchrotron radiation as a light source. An upper limit for the yield is set at 0.1% for the entire photon energy range. This small quantum yield indicates that the contribution of O(1S) to atmospheric OH production is not significant.
