Raman scattering of <scp>L</scp>‐valine crystals

Abstract

Abstract Single crystals of L ‐valine, C 5 H 11 O 2 N, have been studied by Raman spectroscopy at temperatures from 17 to 300 K over the spectral range 20–3300 cm −1 . A tentative assignment of the bands is given. Careful analysis of the Raman spectra suggests that a series of changes in the low‐wavenumber region may be associated with a phase transition undergone by the material, and this possibility is discussed.
