Fig. 6. Molecular displacements originated by two different normal modes. Upper panel: intra-molecular (left) and rotational (right) displacements for the first available normal mode at ∼36 cm^–1. Bottom panel: intra-molecular displacements for the spin coupled normal mode at 241.1 cm^–1. Internal and rotational displacements correspond to 100 and 200 units of normal mode, respectively.
