Comments: Cavity ring-down spectroscopy coupled with pulsed laser photolysis was used to study the visible absorption 
spectrum (490-535 nm) of the phenyl radical, C6H5, in 10-50 Torr of argon diluent at 298 K.
Absorption cross-sections were independent of total pressure over the range studied. 
At 504.8 nm, sigma(phenyl) = (3.6 ± 1.6) × 10-19 cm2 molecule-1 (base e).
