X-ray absorption spectroscopy (XANES and EXAFS) has been used to determine the environment of cations (Ni, Zn, Zr, Fe and Mo) in oxide glasses and their redox state. Direct quantitative structural information can be extracted which indicates that cations are often present in unusually low coordination number compared to crystals. Medium range environment can be assessed with second and further neighbors. This yields to define structural models on the connectivity between cation polyhedra and the network structure.
