Single crystals of L-valine, C5H11O2N, 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.
