Partially deuterated tetramethoxydibenzofuran-hexafluorophosphate: An electron spin resonance study

Abstract The susceptibility of the title compound is large, χ (300 K) = 3.8 × 10 −4 emu/mol, and the temperature dependence of the susceptibility is explained by the random exchange Heisenberg antiferromagnetic chain model. The localization of the electrons in an antiferromagnetic order is proved by the angular dependence of the e.s.r. linewidth, which corresponds to dipole-dipole interaction. A comparison of the spin properties between the title compound and the non-deurated compound exhibits only minor differences.
