UV (240−370 nm) and IR (3200−1500 cm-1) absorption cross-sections of HCHO, HCDO, and DCDO in a bath gas of N2at 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. [ABSTRACT FROM AUTHOR]
