BIBLIOGRAPHY: O.V. Rattigan, O. Wild, and R.A. Cox, "UV absorption cross-sections and atmospheric photolysis lifetimes of halogenated aldehydes", J. Photochem. Photobiol. A: Chem. 112, 1-7 (1998); DOI: 10.1016/S1010-6030(97)00250-5
COMMENTS: Absorption measurements at 243 to 298 K using a diode array spectrometer

Averages over 5-nm intervals of the spectrum measured at a resolution of
∼0.6 nm (FWHM)

Temperature coefficients B for the parameterization

ln σ(T) = ln σ(298 K) + B × (T - 298) at T = 243-298 K:
