Abstract

A Raman spectrum of dry DNA has been recorded in a wide frequency range with a high spatial resolution. The Raman intensity of the low-frequency mode (25 cm−1) of dry DNA is found to exceed the intensity of intramolecular vibrations of nucleic bases and sugar-phosphate backbone by more than an order of magnitude. The position of the low-frequency peak changes with temperature of the DNA under study.
