Peak-fitting of spectra on constituent lines is performed and the basic structural units formed in the system are determined. The conditions for the appearance of highly coordinated germanium atoms are determined, and non-statistical distribution of modifier cations in the studied glasses is found. It is shown that substitution of the lithium cations by potassium cations, firstly, results in a change of the coordination number of Ge atoms, and then a rupture of the GeOGe bonds with the formation of non-bridging oxygen atoms.</p>germanate glassesRaman spectroscopystructure of glassesгерманатные стекласпектроскопия комбинационного рассеянияструктура стекол[Анфилогов В.Н., Бобылев И.Б.
