Abstract

We have performed low-frequency Raman experiments on several polynucleotides with different sequences, conformations, and number of strands per helix. Below 200 cm-1 we have observed three Raman active intrahelical modes in A-DNA and B-DNA. Within one class of structure the modes show little sequence dependence. The bridging hydrogen bonds between the two strands only have a small influence on the frequency of the modes. The modes are strongly dependent on conformation and may therefore be useful as marker bands for structures and intrahelical interactions.
