Abstract

Low-frequency (10–15 cm–1 < v < 200 cm–1) Raman spectra of polycrystalline 1-methyl-cytosine, 1-methyluracil and 1-methylthymine at 300 K have been investigated in detail. The lattice vibrational modes and intramolecular out-of-plane vibrations have been identified. It has been discussed, how the low frequency Raman spectra of nucleic acid bases are affected by their methylation at the point of glycoside linkage.
