Raman spectra of four glasses in the Li_2O-SiO_2 system (41.3*Li_2O*61.3mole%) prepared by rapid quenching were measured. The proportions of SiO_4 units with 1, 2, 3 and 4 non-bridging oxygens per silicon (NBO/Si) and the fractions of bridging oxygens, non-bridgingoxygen and free or fully-active oxygen were estimated for these glasses from the quantitative analysis of the obtained Raman spectra. X-ray structural analysis of the Li_2O-SiO_2 glasses were found to elongate the average atomic distance of Si-O pair with the increase of the Li_2O content due to the weaking of the Si-O bond.
