Abstract: | Direct production of O(3P) from the photodissociation of O3 at 266 nm has been observed by time-resolved resonance fluorescence following laser flash photolysis. The quantum yield for O(3P) production was determined to be 0.12 = 0.02 at this wavelength. This result confirms the qualitative observations of two previous photofragment studies and establishes an absolute value of Φ(O1D)) = 0.88. This value has been used as a basis for normalizing relative quantum yields in the falloff region, and interpreting O(1D) kinetics studies. |
