Wallington, P. Dagaut, M.J. Kurylo Title: Measurements of the gas phase UV absorption spectrum of C2H5O2· radicals and of the temperature dependence of the rate constant for their self-reaction Journal/Source: J. Photochem. Photobiol. A: Chem., 42, 173-185, (1988); http://dx.doi.org/10.1016/1010-6030(88)80061-3 Data: table, diagram Energy/Wavelength range: 215 - 290 nm Resolution: 5-10 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: A flash photolysis technique has been used to measure the gas phase UV absorption cross-sections for C2H5O2· radicals over the wavelength range 215-300 nm. The measured absorption cross-section at 250 nm, is (3.89 ± 0.54) x 10-18 cm2 molecule-1. Author to whom correspondence should be addressed: (e-mail address):
