Title: Investigation of the Absorption Cross Section of Phenyl Radical and Its Kinetics with Methanol in the Gas Phase Using Cavity Ring-Down Spectroscopy and Theoretical Methodologies

Journal/Source: J. Phys. Chem. A, 123, 45, 9682–9692, (2019); https://doi.org/10.1021/acs.jpca.9b09302

Comments: Cavity ring-down spectroscopy (CRDS) was used to measure the absorption cross section of phenyl radicals at 504.8 nm. The absorption cross section was independent of the total 
pressure range (40–200 Torr).
