The electron paramagnetic resonance of VO2+ ion impurities in single crystals of M"Rb2(SO4)2·6H20 where M"=Mg, Fe; MgSO4·7H2O; NaKC4H4O6·4H2O; and (NH4)2C2O4·H2O has been studied at room temperature and at X-band frequency region. Multiple trapping sites for vanadyl are observed in all the crystals. The vanadyl ions enter the lattices at substitutional sites and a correlation is found to exist between the directions of the metal-oxygen bonds and the V-O bonds. The spin-Hamiltonian parameters have been evaluated from single crystal as well as from powder spectra.
