Hancock, P.L. Tyley Title: The near-uv photolysis of ozone: quantum yields of O(1D) between 305 and 329 nm at temperatures from 227–298 K, and the room temperature quantum yield of O(3P2) between 303 and 310 nm, measured by resonance enhanced multiphoton ionisation Journal/Source: Phys. Chem. Chem. Phys., 3, 4984-4990, (2001); DOI: 10.1039/B107018P Data: Energy/Wavelength range: 305 - 329 nm Resolution: Temperature: 298, 273, 247 and 227 K Temperature dependence: yes Pressure/Concentration: Phase: gas pH: Comments: Quantum yields have been measured for the O(1D) fragment from the photolysis of ozone between 305 and 329 nm at temperatures of 298, 273, 247 and 227 K. Measurements of the quantum yield of the O(3P2) fragment between 303 and 310 nm indicate that the short wavelength limiting value of the O(1D) quantum yield at room temperature lies between 0.85 and 0.9.
