Raman data obtained as a function of temperature show that the first uracil in the UUCG tetraloop is stacked and the two middle residues (rU and rC) are in the 2'-endo/anti conformation, in agreement with the previously published NMR results.

Comparison of the data obtained from two highly stable CUUG and UUCG tetraloops containing the same nucleotides but in a different order permitted an overall discussion of their structural features on the basis of Raman marker evidences.

A conclusion was made that for reliable reconstruction of the isolated nucleoside IR spectrum the quasi whole set of conformers should be taken into consideration and this result opens up a possibility to reconstruct IR spectra of isolateducleosides at physiological temperatures with rather satisfactory probability.

The number of hydration considered in the present report is justified due to the opportunity to analyze the vibrational features of these amino acids in hydrated media by means of the density functional theory (DFT) calculations at the B3LYP/6-31++G* level.

Interpretation of DNA vibration modes: IV--A single-helical approach to assign the phosphate-backbone contribution to the vibrational spectra in A and B conformations.

- 1 February 1989
A calculated approach based on the Higgs method for assigning the vibration modes of an infinite helicoidal polymeric chain has been performed on the basis of a reliable valence force field and results clearly show that the phosphate-backbone modes in the above mentioned spectral region constitute the optical branches of the phonon dispersion curves with no detectable variation in the first Brillouin-zone.
