NAME: phenyl radical
FORMULA: C6H5

T: 298K
λ: 504.8nm

COMMENTS: Cavity ring-down spectroscopy (CRDS) was used to measure the absorption cross section of phenyl radicals (C6H5*) at 504.8 nm (2B1 ← 2A1 transition) in the nitrogen atmosphere at 40 Torr total pressure and 298 K using nitrosobenzene (C6H5NO) as the radical precursor

The absorption cross section was independent of the total pressure range (40−200 Torr) over which it was studied with a precursor concentration of (4−5) × 1013 molecules cm−3
