The atomic structure of a series sodium iron phosphate glasses is studied using different experimental techniques: X-ray and neutron diffraction (ND), infrared spectroscopy, extended absorption fine (EXAFS), near-edge (XANES). Detailed information about the pair correlations obtained. high resolution ND in real space resolves two P–O distances at 1.48 ? 1.59 as expected. All are found to consis...
