    Notes: Abstract By calculations based on the Wilson GF-method and using a valence force field, the vibration modes of 5′-dGMP have been assigned. Good agreement was obtained between the calculated and experimental results corresponding to the Raman and infrared spectra of 5′-dGMP. The calculations can also predict the displacement of infrared bands observed upon selective deuteration on C8 and simultaneously on the C8, N1 and N2 atoms of the guanine ring. In order to preserve the harmonic approximation of the potential field, the redundancy between the internal coordinates is entirely removed using a $$B \cdot \tilde B$$ matrix-product diagonalization procedure. In this treatment the local symmetry of different constituents of the molecule is taken into consideration, thus avoiding extensive linear combinations of internal coordinates. The extension of these calculations to the guanosine-moiety involved in the double helix structures of DNAs allowed us to reproduce a certain number of the characteristic guanine vibration modes altered by the B→Z transitions of poly(dG-dC)·poly(dG-dC) and d(CG)3·d(CG)3.

    Out-of-plane vibration modes of nucleic acid bases (1987)
    Springer

    Notes: Abstract The non-planar vibration modes of guanine and adenine, and their C8-deuterated, N-deuterated and perdeuterated analogs have been calculated using a valence force field and a set of non-redundant symmetrical coordinates. Moreover, the effect of 15N isotopic substitution in both pyrimidic and imidazolic rings of guanine has been studied. The calculated wavenumbers are in agreement with the published Raman and infrared spectra. The extension of the force field to the N9-methylated derivatives of guanine and adenine bases has also been described. On the basis of these calculations one can assign the guanine and adenine residue out-of-plane modes observed in the 800–750 cm-1 region in the infrared spectra of the mononucleotides and polynucleotides containing purine bases.

    Notes: Abstract The out-of-plane vibration modes of uracil, cytosine and their deuterated and methylated derivatives such as 1,5-dimethyluracil (1-methylthymine), I-methylcytosine, 5-methylcytosine and 1,5-dimethylcytosine have been computed. The calculated wave-numbers have been compared to the published Raman peak and infrared band positions observed for solid or aqueous samples. The calculations have been carried out on a non-redundant set of symmetrical coordinates and a valence force field has been used. Some characteristic modes located between 750 and 800 cm-1 found in the infrared spectra of 2′-deoxycytidine, 2′-deoxythymidine 5′-monophosphate and polynucleotides containing cytosine and thymine bases can be interpreted from the calculated results on 1-methylthymine and 1-methylcytosine.
