DATAFILE: HCO_Hochanadel(1980)_298K_195-275nm(smoo).txt
NAME: formyl radical
FORMULA: HCO
AUTHOR(YEAR): Hochanadel(1980)
T: 298K
λ: 195-275nm(smoo)
BIBLIOGRAPHY: C.J. Hochanadel, T.J. Sworski, and P.J. Ogren, "Ultraviolet spectrum and reaction kinetics of the formyl radical", J. Phys. Chem. 84, 231-235 (1980); DOI: 10.1021/j100440a001
COMMENTS: A weak transient absorption in the ultraviolet, attributed to the HCO radical, was observed on flash photolyzing CO saturated with H2O vapor

A smooth fit of the measured extinction coefficients plotted in Fig. 2 has been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21)
