Vibrations and stability of nucleotides: guanine

摘要

In this contribution we report on a study of conformational changes of guanine in the temperature range from 300 to 600 K. We have used a new molecular dynamics with charges at bonds and have studied time dependence of interatomic distances for the first and second neighbors at these temperatures. It was fount that the interatomic distances can serve as a criterion for conformational transitions between different conformations. Explanation is based on the theory of stability and theory of parametric resonance.
