A Spectroscopy of Helix Melting.

Abstract

We have calculated the far infrared absorption for several models of double helical DNA. These results are in good agreement with experimental observations. We have also fitted our results to observed inelastic neutron scattering data. Again the results are in excellent agreement with observation. We have extended our calculations on helix strand melting to include methylated DNA and many other DNA's of varying base pair sequence. All of the results are useful in leading to more precise predictions of the dynamics of DNA strand separation in a far infrared radiation field. We have also extended our model so as to predict energy flow in the natural process of RNA transcription. Keywords: Helix melting, Deoxyribonucleic acid, Free electron laser irradiation.
