文摘

UV (240-370 nm) and IR (3200-1500 cm^-1) absorption cross-sections of HCHO, HCDO, and DCDO in abath gas of N₂ at atmospheric pressure and 296 K are reported from simultaneous measurements in the twospectral regions. Cross-sections were placed on an absolute scale through quantitative conversion offormaldehyde to CO and HCOOH by titration with Br atoms, also monitored by FTIR. The integrated UVabsorption cross-sections of HCHO, HCDO, and DCDO are equal to within the experimental uncertainty.
