Electric linear dichroism transients of bent DNA fragments

Mostrar todas las versiones(3)

We study the effect of translational-rotational hydrodynamic coupling on the transient electric linear dichroism of DNA fragments in aqueous solution. As opposed to previous theoretical works, where analytic solutions valid in the limit of low electric field were reported, we present here a numerica...
