Substance: IO Harwood M.H., J.B. Burkholder, M. Hunter, R.W. Fox, A.R. Ravishankara Absorption Cross Sections and Self-Kinetics of the IO Radical J. Phys. Chem., A, 101 (1997), 853-863 Data: Table Temperature: 203 - 373 K Temperature dependence: Wavelengths range: 340 - 480 nm Resolution: Comments: The absorption cross section at the peak of the (4.0) band at 427.2 nm was determined as a function of temperature and is essentially independent of temperature.
