FIG. 1.

Phases (plotted between −180° and +180°) of component amplitudes in lysozyme (left) and DNA (right) from the 3D-RISM scattering profiles. Each value is the average phase for a given magnitude of q, and the error bars report the standard deviation of the distribution of phases for different directions. The phase of the total amplitude is also shown in red. For both systems, at small angle most of the amplitudes are aligned (i.e., in phase), except for the co-ion Cl⁻ in the DNA case, which is excluded from the solute and thus is out of phase.
