LOW-FREQUENCY PHONON RAMAN SPECTRA OF NUCLEIC ACID CONSTITUENTS: PYRIMIDINE BASES

Summary

    Low-frequency (10-15 cm^-1 < v < 200 cm^-1) Raman spectra of polycrystalline cytosine, uracil and thymine at 300 K has been investigated in detail. Lattice vibration bands are identified, and types of symmetry are determined in some cases. Possible applications of obtained results in the field of biophysics are discussed. The authors point out the advantage of using Raman spectroscopy on external degrees of freedom to study structural-dynamical properties of the solid biomolecular complexes as well as for analytical purposes.
