Matrix-isolation study of the vacuum-ultraviolet photolysis of NF3. The electronic spectrum of the NF2 free radical

Abstract

The vacuum-ultraviolet photolysis of NF3 in an argon or a carbon monoxide matrix at 14°K leads to the production of NF2, identified by its infrared absorption. F-atom photodetachment also leads to the appearance of FCO in the carbon monoxide matrix studies. The photodissociation of NF2 by 2537 Å radiation has been confirmed. The appearance of a band system near 2600 Å with position and band spacings close to those previously reported for NF2 in the gas phase demonstrates that the lower state of the gas-phase transition is the ground state of the molecule and confirms the assignment of the observed structure to a progression in the upper-state bending vibration. © 1974.
