Low-frequency Raman spectra of polycrystalline ribonucleosides

D. M. Hovorun, Ya. R. Mishchuk, Ye. P. Yurenko

Firstly obtained low-frequency Raman spectra of all four canonical ribonucleosides — adenosine, guanosine, uridine and thymidine — and desoxythymidine in the polycrystalline state at room tem¬perature are presented. On the basis of the data obtained the conclusion is made about the nature of low-frequency vibrational mode of DNA Raman spectrum, with the frequency about 20 CM .
