INTERPRETATION OF DNA VIBRATIONAL-SPECTRA BY NORMAL COORDINATE ANALYSIS

1. 1. In the following article we undertake a brief review of the most prominent DNA vibrational markers as observed experimentally by Raman and i.r. spectroscopies on polynucleotides and explain how a simplified valence force field can account for the evolution of the DNA vibrational spectra. 2. 2. Our discussion made as a review of our previous investigations on the intepretation of DNA vibration modes, is based on some of the most characteristic and structure dependent DNA vibrational markers. © 1990.
