Raman spectra are presented for twenty proteinogenic amino acids, recorded for solid samples using four different laser wavelengths: 325, 514.5, 632.8, and 785 nm. In general, the intensity patterns are very similar for all excitation wavelengths. The spectra are analysed in terms of similarity. Possibilities of determination of amino acids in multicomponent powder mixtures are discussed and illustrated by examples.
