Raman and Infrared Spectra of β-Alanine

Abstract
The Raman spectrum of β-alanine has been recorded in the single crystal form employing λ 2537 technique. The infrared spectra in Nujol mull and KBr pellet have been taken for the range 400–4000 cm−1. The spectra exhibit the characteristic lines of the zwitter ion and also hydrogen bond vibrations in the region 2400–3000 cm−1. The tentative assignments of the observed lines are given and compared with those of other amino acids.
