The short range order of multicomponent SeO₂ glasses has been studied by neutron scattering. To identify the contribution of SeO₂ diffferent oxides, MoO_3, V₂O_5, Bi₂O₃ were used for glass synthesis. Crystal like model distribution functions were calculated in order to describe the experimental RDFs. It was established that the coordination state of Se in relation to oxygen remains unchanged, n=3. A shortening of Se-O distances in SeO₃ pyramids was observed. These distances change from 1^.78 A in crystalline SeO₂ to 1_{.72 in selenite glasses.
