Abstract:

The infrared, Raman, and polarized micro-Raman spectra of the amino acid L-glutamine and its N,N'-d5 derivative in the crystalline state have been recorded and measured. The data obtained were used to propose a general assignment of the vibrational fundamentals on the basis of the intensity changes observed from the polarized Raman spectra, the isotopic shifts measured from the deuterated isotopomer, and the correlations with frequencies assigned for other amino acids and related molecules.
