Single-crystal samples of L-alanine, CH3CH(NH2)COOH, a fundamental amino
acid of most proteins, have been studied by Raman spectroscopy in a
diamond-anvil cell up to pressures of 43 kbar. From the analysis of
results we observed that the crystal undergoes a phase transition about
22-23 kbar. The transition is accompanied by abrupt changes in the
relative intensity of low-energy bands, by the appearance of a phonon in
the external mode region of the spectrum and by some modifications in
phonons of the internal mode type. (C) 2000 Elsevier Science Ltd. All
