THE FO RADICAL AND PRESSURE REACTIONS OF N2F2
Abstract
Efforts to generate gaseous OF centered upon flash photolysis of CF3COOF at low temperature. Two transient phenomena were found: at 77K violet phosphorescence from the solid and at higher temperature two diffuse adsorption bands from the gas. Because the phosphorescence is observed from the solid of several fluorocarbonyl compounds, the phosphor is likely an impurity excited by energy transfer from the host lattice. For electrolytic generation of OF2 from wet HF, ohmic overvoltage at the nickel anode was determined by both potential decay and superimposed square wave. The ohmic overvoltage at normal electrolysis conditions was surprisingly low (0.25 to 0.40 v. at 4.8 v. anode). Work continued on the structure of N2F2 complexes. Solutions of N2F2 in SbF5, blue when fresh but rapidly fading to yellow, were examined by electron paramagnetic resonance to determine if the color arises from free radicals. An EPR spectrum of the yellow solution could be resolved into two separate spectra. The sixteen-line spectrum is consistent with the SbF5(-) radical while the five-line spectrum arises from an N2 containing radical of as yet unknown composition.
