Absorption cross sections and temperature coefficients from C.A. Cantrell, J.A. Davidson, A.H. McDaniel, R.E. Shetter, and J.G. Calvert, "Temperature-dependent formaldehyde cross sections in the near-ultraviolet," J. Phys. Chem. 94, 3902-3908 (1990); DOI: 10.1021/j100373a008 . High-resolution data averaged over the 2.5-nm intervals 300.0-302.5, 302.5-305.0,........., 355.0-357.5nm; first column: center of interval. The temperature dependence between T = 223 and 293 K can be calculated by the relation σ(T) = A + B × (T - 273) = σ(273 K) + B × (T - 273) with the parameters: -------------------------------------------------------------------
