Vibrational Spectra (IMAGE) Forschungsverbund Berlin Caption This is the two-dimensional vibrational spectra of RNA (upper panel) and DNA (lower panel) in the frequency range of the sugar-phosphate vibrations of the backbone. The RNA spectrum displays additional bands (contours) along the frequency diagonal ν1=ν3 and a more complex distribution of off-diagonal peaks. In addition to the frequency positions the line shapes of the individual bands (contours) give insight in details of the interactions with neighboring water molecules.
