Abstract

Relative quantum yields for the formation of O 1D from the photolysis of ozone have been measured between 301 and 336 nm. O 1D was monitored indirectly, using laser induced fluorescence detection of vibrationally excited OH. The OH was produced by the reaction of O 1D with H2. The observation of 'blue-shifted' laser induced fluorescence provided high detection sensitivity and eliminated probe laser interference effects. The results confirm that there is a significant quantum yield for O 1D production at wavelengths longer than 320 nm. A measurable yield is observed out to 336 nm providing evidence for spin-forbidden production of O 1D.
