摘要
%26quot;Anomalous changes%26quot; 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.
