Strong effect of hydrodynamic coupling on the electric dichroism of bent rods
Article Abstract:
The effect of hydrodynamic coupling on the spatial orientation of rigid bent rods in electric fields is analyzed by Borwnian dynamics simulations. Bead models for smoothly bent rods were constructed with dimensions of DNA double helices, and established simulation procedures used to calculate their diffusion tensor, including the translational-rotational coupling tensor.

Unique physical signature of DNA curvature and its implications for structure and dynamics
Article Abstract:
An improved birefringence technique is used for measuring the electrooptical data of curved DNA at low electric field strengths over a wide range of ion concentrations. A clear increase of the curvature is observed with the increase in salt concentration.

Dipole reversal in bacteriorhodopsin and separation of dipole components
Article Abstract:
The electrostatics of purple membranes was analyzed by measurements of the electric dichroism in dc and ac fields in a broad pH range. The minimum value of the dichroism indicates the permanent dipole and shows a complex dependence on the pH.
