Streszczenie

The solvent effect on hyperfine interaction in three different types of iminoxy radicals obtained by oxidation of di-2-pyridiketoxime ( 1), diethyl hydroxyimino(2-fluorophenyl)methanephosphonate ( 2) and isonitrosoacetophenone ( 3) have been analyzed. Linear correlations of hyperfine constants of 14N (both iminoxyl and pyridyl nitrogens of the iminoxyl derived from 1), 31P (isomer Z of the iminoxyl derived from 2) and 19F (both Z and E isomer of iminoxyls derived from 2 on E T (30) solvent parameters have been found. Opposite directions of the dependencies for different nuclei of the same radical have been established. Anisotropic spectra of the radical derived from 1 and iminoxy radicals derived from α-furildioxime have been obtained by γ-irradiation of solid oximes.
