Title: UV absorption cross-sections and atmospheric photolysis rates of CF3I, CH3I, C2H5I and CH2ICl

Journal/Source: J. Chem. Soc., Faraday Trans., 93, 16, 2839-2846, (1997); doi: 10.1039/A701529A


Data: diagram, table

Energy/Wavelength range: 235 - 365 nm

Resolution: 5 nm

Temperature: 298 K

Temperature dependence: The temperature dependence of the cross-sections was investigated over the range 333-243 K

Pressure/Concentration:

Phase: gas

pH:

Estimated Error: 


Comments: A decline in the cross-section with decreasing temperature at wavelengths longer than ca. 280 nm was observed in all cases, the 
decrease being most pronounced in the long wavelength tail of the absorption band.
