Structure-spectrum correlations in nucleic acids. I. Raman lines in the 600-700 cm-1 range of guanosine residue.
Raman spectra of nine crystals of known structures which involve guanosine moieties with various conformations have been observed. It has been established that a guanosine residue with the C3'endo-anti conformation gives a strong Raman line at 666 +/- 2 cm-1. It has also been found that the residue with 04'endo-anti gives a strong Raman line at 682 cm-1, and C3'exo-syn at 616 cm-1. The usefulness of these structure-spectrum correlations in the conformation studies of polynucleotides are shown.
