BIBLIOGRAPHY: O.V. Rattigan, D.E. Shallcross, and R.A. Cox, "UV absorption cross-sections and atmospheric photolysis rates of CF3I, CH3I, C2H5I and CH2ICl", J. Chem. Soc. Faraday Trans. 93, 2839-2846 (1997); DOI: 10.1039/A701529A
COMMENTS: Absorption measurements at 243, 253, 263, 273, 298, 313, and 333K with a spectral resolution of 0.6nm (FWHM) using a diode array spectrometer

Calculated absorption cross sections using the values measured at 298 K, the equation

ln σ(T) = ln σ(298K) + B × (T - 298)

and the temperature coefficients B (243-333 K):
