DATAFILE: CH2O_MellerMoortgat(2000)_223-323K_249.38-356.56nm(T-gradient).txt
NAME: formaldehyde, methanal
FORMULA: CH2O
AUTHOR(YEAR): MellerMoortgat(2000)
T: 223-323K
λ: 249.38-356.56nm(T-gradient)
BIBLIOGRAPHY: R. Meller and G.K. Moortgat, "Temperature dependence of the absorption cross sections of formaldehyde between 223 and 323 K in the wavelength range 225-375 nm", J. Geophys. Res. 105(D6), 7089-7101 (2000); DOI: 10.1029/1999JD901074
COMMENTS: Empirical fit of the temperature dependence (223-323 K):

σ(λ, T) = σ(298 K) + Γ × (T - 298 K)

with the temperature coefficients Γ (in cm2 molecule-1 K-1) listed in the second column
