The radical photodissociation channel of acrylonitrile Academic Article uri icon

abstract

  • We have measured nascent Doppler profiles of CN (X2+) fragments from the 193 nm photodissociation of acrylonitrile using transient frequency-modulation spectroscopy. The Doppler profiles exhibit no v or v j correlations, and are consistent with the CN velocity distributions expected for a statistical, ground state dissociation. About 12% of the CN fragments have a single quantum of vibrational excitation, greater than the statistical prior prediction. However, the overall pattern of energy disposal and vector correlations is more consistent with a ground state, statistical fragmentation than a prompt, excited state dissociation. The CN quantum yield is 0.003 0.001 at 193 nm.
