Figure 3: HS normal modes.
From: Coherent structural trapping through wave packet dispersion during photoinduced spin state switching
(a) Fe-N bond coordinate and average length r for a1g and eg symmetry normal modes. (b–f) Respective representation of normal breathing mode (124.4 cm−1, in-phase stretching of the 6 Fe-Ni bonds with almost rigid bpy ligands), the global stretching mode (353.4 cm−1, bpy and Fe-N stretching), stretching modes at 114.8 and 115.9 cm−1 and a bending mode at 138.8 cm−1. Green arrows show N motions and grey ones ligand motions. (g–i) Time evolution of the symmetry independent bonds r1, r2 and r3 with respect to inversion symmetry and their average r (purple).
