Abstract
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 O4′endoanti 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.Keywords
