LASER RAMAN, FTIR SPECTROSCOPIC INVESTIGATION AND INFRARED LIGHT TESTING OF M2SO4 (M K, NH4, Li) DOPED TRIGLYCINE SULPHATE(TGS) CRYSTALS
Abstract
- In this paper, crystals of undoped Triglycine Sulphate, (NH2CH2COOH)3.H2SO4, (abbreviated as TGS) and M2SO4 (where M = K, NH4, Li) doped TGS have been grown by solution growth method. The grown crystals were characterized by laser Raman and FTIR spectroscopy to study the vibrational characteristics of the various functional groups present in the crystals. Laser Raman spectra were observed by Ocean Optics E65000 Visolator Raman Spectrophotometer. FTIR spectra were observed by using Perkin-Elmer Spectrum-100 FTIR Spectrophotometer. Vibrational characteristics and mode assignments of constituent molecules of SO42-, COO-, CC, CO2CH2CH2, NHNH3, NH3 and CO2 were reported. Furthermore, infrared (IR) light transmission experiments were tested by using laboratory-prepared IR driving circuit to show the IR windows materials.
