. Raman measurements were performed in the range of 200-2000cm

at room temperature. Raman and Infrared spectroscopy was utilized for structural study of this glass system. Specific modes of vibration and peak position were identified from de-convolution of infrared and Raman spectra using Gaussian fitting. Ge-O-Ge bonds' symmetrical stretching vibrations related to 3 members GeO
