Reverse Monte Carlo (RMC) simulation has been carried out in order to estimate the partial structural functions of Ge–Ge, O–O and Ge–O pairs for GeO2 glass. Three independent interference functions from the ordinary X-ray diffraction, neutron diffraction and anomalous X-ray scattering measurements near Ge K absorption edge were used in the RMC simulation. The present results clearly indicate that the GeO2 glass structure can be described by a continuous random network of corner-shared GeO4 tetrahedral units as detected in the α-quartz type of GeO2 crystal.
