✦ Synopsis

We report the rotational and vibrational quantum state distributions of the CN (X 2,~ +) product formed in the 193 nm photolysis of acrylonitrile (vinyl cyanide). The CN product is formed in v = 0 and v = I with relative populations of 0.86 and 0.14, respectively. The rotational distributions in both v-levels are well fit to a temperature of approximately 1450 K. The results are consistent with a prompt dissociation on the excited electronic potential surface.
