Infrared Spectrum and Thermodynamic Functions of the NF2 Radical

Abstract

The three fundamental vibrational frequencies for the NF2 radical have been measured in an N2 matrix at 20°K. They are ν1 = 1069.6±0.5, ν2 = 573.4±1.0, and ν3 = 930.7±0.5, all in cm−1. The infrared spectrum of N2F4 was also examined and good evidence is presented to confirm that N2F4 dissociates into NF2 at low pressures. This dissociation was found under the conditions in our spray‐on line to have a half‐life of 100 sec or more at room temperature and about 1 sec near 100°C. The thermodynamic functions of NF2 are tabulated.
