摘要：

Iminoxy radicals containing the diethyl phosphonate group have been synthesized and characterized by means of EPR spectroscopy. Structures of the Z and E isomers have been established on the basis of hyperfine splitting due to N-14, P-31, and H-1 nuclei. The higher stability of the E isomer over the Z isomer has been established by analysis of anisotropic spectra. The source of a dependence of the P-31 hyperfine constant on the solvent polarity is discussed.
