Title: Photolysis of ozone at 308 and 248 nm: Quantum yield of O(1D) as a function of temperature

Journal/Source: Geophys. Res. Lett., 24, 1091-1094, (1997)


Data: 

Energy/Wavelength range: 248 nm, 308 nm

Resolution: 

Temperature: 200 - 320 K

Temperature dependence: yes

Pressure/Concentration:

Phase: gas

Comments: The quantum yield of O(1D), PHI(T), in the 308 nm photolysis of ozone has been shown to decrease very slightly 
with temperature (T), from 0.79±0.10 at 298 K to 0.73±0.10 at 200 K. At 248 nm, PHI is (0.91±0.06) independent of temperature (200–320 K).
