Figure 13

The evolution of charge distribution with uniaxial stress along the x direction. The first column shows the two lowest E_1u modes of unstressed heptamer and the B_1u mode. Second and third columns show B_2u and B_3u modes of the heptamer under 10% and 30% strains, respectively. The resonance wavelengths of the heptamers are also shown. (From Ref. [21])
