摘要：

Vibrationally excited HCO radicals have been observed in the photodissociation of acetaldehyde in a supersonic jet with the pump-probe technique. The threshold wavelength for the bending and CO-stretching excitations was 308.7 and 302.6 nm, respectively. The nascent vibrational distribution relative to the ground state has been determined as a function of the excitation wavelength for the 280-300 nm region. The observed vibrational distribution of HCO was found to be consistent with the model in which the excess energy above the reaction barrier is statistically distributed among the fragments' degrees of freedom.
