Abstract
Single crystals of triglycine sulphate doped with different concentrat ions of alanine were studied by Raman spectroscopy, Bands due to the s ubspecies modes from the three crystallographically distinct glycine i ons in the lattice were identified. The anisotropy measurement in spec ific Raman scattering geometries as a function of concentration of ala nine allow us to infer that alanine preferentially replaces glycine-I ions and induces realignment of other glycine units in the lattice.
