Rowley, P.D. Lightfoot, R. Lesclaux, T.J. Wallington Title: The UV absorption spectrum and self reaction of cyclopentyl peroxy radicals Journal/Source: J. Chem. Soc. Faraday Trans., 88, 1369-1376, (1992); DOI: 10.1039/FT9928801369 Data: diagram, table Energy/Wavelength range: 210 - 300 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The spectrum of c-C5H9O2 is similar to those of other alkylperoxy radicals, with a maximum cross-section of (5.22 ± 0.20) x 10-18 cm2 molecule-1 at 250 nm, measured relative to a value of 4.55 x 10-18 cm2 molecule-1 for CH3O2 at 240 nm.
