A self-consistent microscopic theory of hydrogen bond melting with application to poly(d G)⋅poly(d C)

In this paper we develop a modified self-consistent phonon approximation model which displays effects which indicate melting. The model is applied to hydrogen bond melting of poly (dG)⋅poly(dC) and predicts melting at 340 K. The calculation has no parameters adjusted to fit the melting, the hydrogen bond potentials are adjusted to fit data at room temperature.
