An EPR Study of the Tetrafluorohydrazine‐Difluoramino Equilibrium

The EPR spectrum of the difluoramino radical (NF2) was observed to be a single broad line at a pressure of 20–40 mm of N2F4 and a temperature of 340–435°K. The peak‐to‐peak linewidth was observed to be 104 gauss with a g value of 2.010. From the temperature dependence of the line amplitude, the ΔH of dissociation of N2F4 was calculated to be 19.3±1.0.
