Abstract
Time-resolved IR emission spectroscopy (TRIES) has been used to study infrared emission in the 3400-3100 cm-1 region from HCN molecules prod uced when CN radicals abstract a hydrogen atom from ethane, propane, a nd chloroform. From these observations the nascent vibrational distrib utions of the HCN produced were derived. The nascent vibrational popul ation distributions of the product HCN in all of the reactions are non -statistical and inverted in both the pure CH stretch (00p) and CH str etch-bend (0np) series.
