The vibrational Raman optical activity (ROA) spectra of the simple amino acids L-serine, L-cysteine, L-valine, L-threonine and L-isoleucine in aqueous solution between 600 and 1600 cm−1 measured in backscattering are presented and discussed. Complete vibrational assignments are suggested for serine and cysteine and limited assignments for the others. Bands originating in Cα*H deformations and the symmetric CO2− stretch appear to provide the best signatures for stereochemical studies. The results show that ROA provides a new perspective on amino acid conformation in aqueous solution.
