Abstract

We have performed Brillouin and low-frequency Raman experiments on the oligonucleotide crystals d(CGCGAATTCGCG) and d(GGTATACC). The Raman spectra below about 40 cm^-1 are different from fiber spectra due to changes in crystal packing in the octamer and small changes in interhelical interactions in the dodecamer. The modes between 50 and 120 cm^-1 seem to depend more on intrahelical interactions rather than crystal packing forces. These modes may prove to be useful as marker bands for both interchain and intrachain interactions in oligonucleotide crystals and fibers.
