The results of an electron paramagnetic resonance (EPR) study of vanad
yl ion VO2+ doped in single crystals of Ba (ClO4)(2) . 3H(2)O are repo
rted. The spectra indicated the presence of two substitutional and int
erstitial sites depending on the orientation. The spin-Hamiltonian par
ameters were determined from single crystal and powder EPR data. These
parameters were found to be axial symmetric for the powder sample, wh
ereas they showed deviations from axial symmetry for the single crysta
l.
