The chemistry of trifluoramine oxide. VII. Photolytic Generation and electron spin resonance spectra of F2NO radicals

Abstract Photolysis of solid F 3 NO at −196° produces the F 2 NO radical identified by its 9-line ESR spectrum consisting of a fluorine split 1:2:1 triplet (a F = 143.0 G), each component of which is further split by 14 N into 1:1:1 triplets (a N = 94.5 G), with g = 2.0093. Trifluoramine oxide enriched with 15 N provided the expected 6-line spectrum of F 2 15 NO comprised of the fluorine triplet (a F = 142.6 G) each component of which is further split by 15 N into doublets (a N = 132.3 G), with g = 2.0094. The data are best interpreted in terms of a pyramidal structure for F 2 NO.
