1) No temperature stated; 298 K is presumed.
2) The measured energy distributions of CN are well represented by statistical prior calculations, assuming the CN and allyl radical products rather than the propenyl isomer. Ab initio calculations were performed for the relevant product species and transition states for isomerization and CN elimination. It has been concluded that methacrylonitrile dissociates in the ground electronic state via allyl cyanide formed by CN and H atom migration prior to dissociation.
