Silver nanoparticle heptamer. (a) Symmetry adapted basis functions of heptamer in-plane modes belonging to the D 6h point group. (b) Scattering and (c) absorption spectra calculated with the finite element method for heptamers with various sizes. The dashed curves show the red-shift of the dark (green) and bright (blue) modes with increasing size. (From Ref. [115])
