Abstract
The photodissociation of acetyl and propionyl radicals at 248 and 266 nm has been studied by time-resolved Fourier transform infrared spectr oscopy. A vibrationally excited product CO(v less than or equal to 8) was observed in the emission spectra. The vibrational temperatures of the nascent CO products were about 7400 K for the acetyl radical and 6 930 K for the propionyl radical. The vibrational energy partitioning o f the CO fragments fits a soft impulsive model. (C) 1997 American Inst itute of Physics.
