DATAFILE: CH3_Slagle(1988)_296-906K_216.36nm.txt
NAME: methyl radical
FORMULA: CH3
AUTHOR(YEAR): Slagle(1988)
T: 296-906K
λ: 216.36nm
BIBLIOGRAPHY: I.R. Slagle, D. Gutman, J.W. Davies, and M.J. Pilling, "Study of the recombination reaction CH3 + CH3 → C2H6. 1. Experiment", J. Phys. Chem. 92, 2455-2462 (1988); DOI: 10.1021/j100320a015
COMMENTS: Pulsed photolysis of acetone; the radicals were detected at 216.36 nm at a resolution of 0.6 nm

Over the temperature range 296-577 K, a linear function was used to describe the temperature dependence:

1017σ(cm2 molecule-1) = 5.90 - 5.95×10-3 T (K)

At higher temperatures (>700 K), a quadratic dependence is required:

1017σ/cm2 = 7.58 - 1.29×10-2(T/K) + 7.28×10-6(T/K)2
