The structure of gamma-irradiated (Li2O)(0.1)(SiO2)(0.9) glass has been studied with two-dimensional hyperfine sublevel correlation spectroscopy (HYSCORE). The theoretical evaluation of the HYSCORE experimental data revealed the existence of weak couplings between the electron spin and nearby ii. The anisotropic hyperfine coupling T is equal to 4.0 MHz suggesting a nonbridging oxygen-Li distance of 2.0 Angstrom and an angle of +/-60 degrees away from the g(z) axis. The A(iso) value is equal to 0.5 MHz, corresponding to 0.135% contribution of the ii 2s orbital to the ground state. Thus, an estimation can be made of the covalent character of the bond between the nonbridging oxygen and the alkali.
