Abstract: Cavity ring-down spectroscopy (CRDS) was used to calculate the electronic absorption spectrum of the allyl radical (CH2CHCH2) between 370 and 420 nm at 297 K. In conclusion, the absorption cross-section of the allyl radical at 402.9 nm was determined to be (2.0 plusmn 0.04) x 10(super -19) cm(super 2) molecule(super -1) through study of time-dependent absorption traces.
