Raman Spectrum of γ-Glycine

Abstract Using λ 2536.5 excitation the Raman spectrum of single crystal of γ-glycine has been recorded for the first time. Thirty-nine Raman frequencies have been reported. Comparing the spectrum of γ-glycine with its infrared absorption spectrum and also with the Raman spectrum of α-glycine, proper assignments have been given to the internal frequencies. The lattice lines observed in Raman effect and infrared absorption have been satisfactorily accounted for.
