    The short range order of multicomponent SeO2 glasses has been studied by neutron scattering. To identify the contribution of SeO2 diffferent oxides, MoO3, V2O5, 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.
