✦ Synopsis

Time-resolved IR emission spectroscopy (TRIES) has been used to study infrared emission in the 3400-3 100 cm-r region from HCN molecules produced when CN radicals abstract a hydrogen atom from ethane, propane, and chloroform. From these observations the nascent vibrational distributions of the HCN produced were derived. The nascent vibrational population distributions of the product HCN in all of the reactions are non-statistical and inverted in both the pure CH stretch (00~) and CH stretch-bend (Onp) series.
