Resolving orientational ambiguities using two media. (A) possible relative orientations for a helix and hairpin fragment using C12E5-CTAB as a medium. (B) possible relative orientations for the same helix and hairpin fragments using C12E5 as a medium. All structures in (B) have been rotated to superimpose helix orientations. Only the relative orientation shown as the first hairpin structure is seen in both media.
