Abstract

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