Vibrational spectra of crystalline β-alanine

Abstract

Infrared (IR) and Raman spectra (RS) of β-alanine single crystal and polycrystalline samples have been measured in the 4000–10 cm −1 range. Factor-group analysis have been made and the number of normal vibration modes was calculated. The assignment of the observed vibrational frequencies to corresponding symmetry type and the molecular fragments have been performed.
