Controlled Unwinding of the Double Helix.

Abstract

We are assembling experiments designed to pump vibrational models of DNA in the 80 per cm frequency region. Modes of this frequency stretch the bridging hydrogen bonds. We will pump these mode both with Stimulated Raman Scattering (SRS) and directly with radiation from a free electron laser (FEL). We will monitor ultraviolet absorption, as the DNA is pumped, in order to see if unwinding occurs. Initial Raman studies indicate that interhelical contacts may influence the 'melting' modes of DNA.
