Research output: Contribution to journalArticlepeer-review


Infrared absorption cross sections for acetone (propanone), CH3C(O)CH3, have been determined in the 3 mu m spectral region from spectra recorded using a high-resolution FTIR spectrometer (Bruker IFS 125 FIR) and a multipass cell with a maximum optical path length of 19.3 m. The spectra of mixtures of acetone with dry synthetic air were recorded at 0.015 cm(-1) resolution (calculated as 0.9/MOPD using the Bruker definition of resolution) at a number of temperatures and pressures (50-760 Tort and 195-296 K) appropriate for atmospheric conditions. Intensities were calibrated using three acetone spectra (recorded at 278, 293 and 323 K) taken from the Pacific Northwest National Laboratory (PNNL) IR database. (C) 2010 Elsevier Ltd.
