  • Title: An interpretation of the "anomalous" changes in the low-wavenumber range of the Raman spectra of L-alanine crystals.
    Author: Kolesov BA, Boldyreva EV.
    Journal: Chemphyschem; 2013 Aug 05; 14(11):2525-8. PubMed ID: 23728861.
    Abstract:
    "Anomalous changes" in the temperature- and pressure- dependences of the intensities and wavenumbers of the two low-wavenumber modes in Raman spectra of single-crystals of L-alanine have been interpreted in terms of a change in relative contributions of stretching and deformational components into the intermolecular vibrational bands. The relative contributions of the two components into a lattice vibration result from a change of relative orientations of molecules linked by hydrogen bonds in a three-dimensional network on variations of temperature or pressure.
