Optical Properties of a Single NR Dimer.
(A) TEM images at different magnifications of a single twisted dimer and (B) correlated dark-field scattering image of the same single dimer as in (A). (C, D) Optical properties of a single SCI-assembled NR dimer as characterized by (C) the dark-field scattering spectrum and (D) the circular dichroism spectrum.
