Abstract
A series of infrared absorption cross-sections for acetaldehyde has been measured in the 3γm region from spectra obtained using a high-resolution Fourier transform spectrometer (Bruker IFS 125/HR). Results presented are for mixtures of acetaldehyde vapor combined with pure synthetic air taken at various temperatures and pressure to simulate atmospheric conditions found principally in the Earth's troposphere and lower stratosphere. Spectra were recorded at a resolution of 0.005cm and intensities were calibrated using three acetaldehyde spectra (measured at 278, 298 and 323K) provided by the Pacific Northwest National Laboratory (PNNL) IR database. © 2010 Elsevier Ltd.
