Description

ESR spectra of VOBr2 solutions in absolutized alcohols ROH (R - Me, Et, i-Pr) and aqueous solutions in the presence of LiBr and HBr are investigated and parameters of spin-hamiltonian of vanadium oxocomplexes are determined. Stabilization of [VOBr(ROH)4]+ complex, in which bromide-ion occupies position in xy plane, is detected. Isotropic additional HFS from 79,81Br atoms at the temperature close to the solution boiling point is found, and at 77 K -anisotropic additional HFS in the range of transitions corresponding to perpendicular orientation of particles as to magnetic field
