This paper describes EPR studies on x V{sub 2}O{sub 5}-(40-x)ZnO-60B{sub 2}O{sub 3}(where x 5, 10, 15 and 20 mol %) glass system. These studies indicate a strong compositional dependent trend and existence of characteristic boro-vanadate groups in these glasses. The EPR spectra show a distinct hyperfine structure of {sup 51}V. Spectral analysis shows that the vanadium is present in the glass as vanadyl ion [VO]{sup 2+} at tetragonally distorted octahedral site. The decrease of A{sub ||} and A{sub perpendicular} with increase of V{sub 2}O{sub 5} concentration suggests an increase in the covalence between the central atom and the surrounding oxygen ligands.
