NAME: benzyl radical
FORMULA: C6H5CH2
AUTHOR(YEAR): MatsugiMiyoshi(2012)
T: 295-800K
λ: 447.7nm(fit)
BIBLIOGRAPHY: A. Matsugi and A. Miyoshi, "Kinetics of the self-reactions of benzyl and o-xylyl radicals studied by cavity ring-down spectroscopy", Chem. Phys. Lett. 521, 26-30 (2012); DOI: 10.1016/j.cplett.2011.11.043
COMMENTS: Absorption measurements over the temperature range 295-800 K using cavity ring-down spectroscopy

A least-squares polynomial fit for the temperature dependence of the absorption cross section was derived:

σ(447.7 nm, T) =
(5.17 ± 1.01)×10-18 exp (4.632 - 1.898×10-2 T + 1.113×10-5 T2) cm2 molecule-1
