Abstract

A tandem Fabry-Perot interferometer has been used to locate Raman bands at 12 cm-1 (B-DNA) and 15 and possibly 12 cm-1 (A-DNA). The Raman shift of these bands is dispersionless and the scattering process appears to require quasimomentum conservation. We assign these bands to the lowest-lying Raman-active optic phonons.
