Epr Study of the 10-Tungsto-2-vanado(Ⅳ, Ⅴ)phosphate Anion, [PV(Ⅳ)VW10O40]6-
Chul Wee Lee, Hyunsoo So*, Kyu Ryong Lee
The polycrystalline epr spectrum of α-1,2-[PV(Ⅳ )ⅤW10O40]6- doped into host crystals and its solution spectrum are reported. The solution spectrum consists of fifteen lines, indicating that the unpaired electron is hopping fast between the two vanadium atoms. The polycrystalline spectrum, which consists of three sets of fifteen lines, was analyzed as a spectrum of an I = 7 system and the epr parameters were determined. The spectrum cannot be interpreted by assuming that each line appears at the average magnetic field of two hyperfine lines expected for two uncoupled vanadium atoms.
