Bass, L.C. Glasgow, C. Miller, J.P. Jesson, D.L. Filkin Title: Temperature dependent absorption cross sections for formaldehyde (CH2O): The effect of formaldehyde on stratospheric chlorine chemistry Journal/Source: Planetary and Space Science, 28 (7), 675-679, (1980); http://dx.doi.org/10.1016/0032-0633(80)90112-9 Data: diagram, table Energy/Wavelength range: 261.45 - 355.00 nm Resolution: Temperature: 223 K; 296 K Temperature dependence: yes Pressure/Concentration: Phase: vapor pH: Comments: Measurements are reported of the absorption cross sections of formaldehyde at 296 K and 223 K. These measurements are significantly lower than those reported in the earlier literature at ca. 353 K. Author to whom correspondence should be addressed: (e-mail address):
