NAME: 2-chloroallyl radical
FORMULA: CH2=CClCH2
AUTHOR(YEAR): AtkinsonHudgens(2000)
T: 298K
λ: 240nm

COMMENTS: Laser photolysis of allene-chlorine mixtures and cavity ring-down detection of the CH2=CClCH2 radical

The absorption spectrum, absorbance vs. wavelength, at 238-252 nm is shown in Fig. 1

The absolute absorption cross section at 240 nm was measured relative to the absorption cross section of the C2H5O2 radical.
