NAME: acetyl radical
FORMULA: CH3C(O)
AUTHOR(YEAR): Cameron(2002)
T: 298K
λ: 190-248nm
BIBLIOGRAPHY: M. Cameron, V. Sivakumaran, T.J. Dillon, and J.N. Crowley, "Reaction between OH and CH3CHO. Part 1. Primary product yields of CH3 (296 K), CH3CO (296 K), and H (237-296 K)", Phys. Chem. Chem. Phys. 4, 3628-3638 (2002); DOI: 10.1039/B202586H
COMMENTS: The absorption spectrum was measured using a diode array spectrometer and normalized to the result from the single wavelength experiment, σ(220 nm) = 1.4×10-17 cm2 molecule-1

The listed absorption cross sections were calculated using the fit of the experimental data to the semi-logarithmic Gaussian function
(information obtained by personal communication from John Crowley, December 2008)

σ(λ) = a1 exp{ -a2 [ln(a3/λ)]2} with

a1 = 1.549×10-17 cm2 molecule-1
a2 = 129.19
a3 = 213.985 nm
