REACTION: formaldehyde → H+HCO
CH2O → H+HCO
AUTHOR(YEAR): Smith(2002)
T: 298K
λ: 268.75-338.75nm
BIBLIOGRAPHY: G.D. Smith, L.T. Molina, and M.J. Molina, "Measurement of radical quantum yields from formaldehyde photolysis between 269 and 339 nm", J. Phys. Chem. A 106, 1233-1240 (2002); DOI: 10.1021/jp013180n
COMMENTS: The relative quantum yields of the radical products H and HCO were obtained by conversion to HO2 using chemical amplification and subsequent detection by CIMS (chemical ionization mass spectrometry). The quantum yields were normalized to 0.753 at 303.75 nm based on the recommendation of JPL Publ. 97-4 (DeMore et al. 1997).
