Vibrational spectra of aminoacid single crystals of a-glydne, (5-alanine, L-histidine, DL-tryptophane in the range of 10–400 cm–1 have been investigated. Vibrations were investigated by IR absorption and Raman scattering methods. In. IR spectra the intensive wide-band absorption was discovered. Relatively narrow bands whose number is in agreement with calculations or slightly exceeding them were registered against its background. In Raman spectra the number of the bands observed is significantly exceeding the calculated one obtained by X-ray structural analysis for ideal crystals. A number of vibrations have been observed by us for the first time. The analysis of the vibrations under study and their assignment to inter- and intramolecular modes was-carried out.
