Characterization of some glasses in the system SiO2, Na2O·RO by infrared spectroscopy

UV-Visible and IR Spectroscopic Studies of Gamma Irradiated Transition Metal Doped Lead Silicate Glasses

“…5 are familiar and evident to be characteristic of the silicate chains which are active in the mid region of the spectrum (400-1,600 cm −1 ). The spectrum of the base lead silicate glass resembles to a great extent the IR spectrum published for soda lime silicate glass [50][51][52][53][54][55][56]. The IR spectrum can be realized and interpreted as follows: a) A broad medium band centered at 460-480 cm −1 is attributed to bending vibrations of Si-O-Si linkages [50][51][52][53][54][55][56].…”

“…b) A small overlapped band at 480-490 cm −1 may be correlated with Pb-O stretching vibration in PbO 4 structural units [57][58][59]. Also a small band at about 510 cm −1 is assigned to Pb-O symmetrical bending vibrations [58,59] [50][51][52][53][54][55][56]. g) A small band at about 1,620-1,650 cm −1 is related to molecular water [50,56,62,63].…”
