COMMENTS: | IUPAC(2013) recommendation:
Averages over the spectral intervals of 500 cm-1 and 5 nm used in atmospheric modelling calculations of the high-resolution absorption spectrum measured by
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
The fourth column shows the temperature coefficients 1024Γ in cm2 K-1 for the empirical fit of the temperature dependence (223-323 K)
σ(λ, T) = σ(λ, 298 K) + Γ × (T - 298 K)
