DATAFILE: HO2_Hochanadel(1972)_296K_185-260nm.txt
NAME: hydroperoxy radical
FORMULA: HO2
AUTHOR(YEAR): Hochanadel(1972)
T: 296K
λ: 185-260nm
BIBLIOGRAPHY: C.J. Hochanadel, J.A. Ghormley, and P.J. Ogren, "Absorption spectrum and reaction kinetics of the HO2 radical in the gas phase", J. Chem. Phys. 56, 4426-4432 (1972); DOI: 10.1063/1.1677885
COMMENTS: Flash photolysis of H2O vapor (3%) in an atmosphere of H2, He or Ar containing ∼2% O2

Original values for the extinction coefficients plotted in Fig. 3 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21)
