Quantum Yields / Organics (carbonyls) / Aldehydes(aliphatic) / CH2O → (total) / Roeth(2015)_300K_250-360nm

DATAFILE: CH2O{(total)}_Roeth(2015)_300K_250-360nm.txt
REACTION: formaldehyde → total
CH2O → (total)
AUTHOR(YEAR): Roeth(2015)
T: 300K
λ: 250-360nm
BIBLIOGRAPHY: E.-P. Röth and D. H. Ehhalt, "A simple formulation of the CH2O photolysis quantum yields", Atmos. Chem. Phys. 15 (2015) 7195-7202; DOI: 10.5194/acp-15-7195-2015
COMMENTS: Fit through literature data at 1013 hPa using the formula from Table 1:

φ(tot)=1/(1+exp(-(1/λ-1/346.9)/5.4E-5)*M/M0) - 0.22/(1+exp(-(1/λ-1/279.0)/5.2E-5))

with: λ = wavelength [nm], M = number density of the bath gas [cm-3], and M0 = number density at 1013 hPa and 300 K [cm-3].
