Scientific Journal of Samarkand University


The article presents the results of studying the complexity of the Raman spectra of a-alanine in the crystalline state. It has been shown by ab initio calculations that the change in the Raman spectra is explained by the formation of several types of hydrogen bonds. In Raman spectra, the presence of a hydrogen bond between molecules is manifested in the form of asymmetry and splitting of vibrational bands.
