Figure 1. An ab initio molecular dynamics simulation of C-C bond formation subsequent to the collision of DME with an SMS. (A) The two-dimensional free energy surface and minimal energy path associated with the first C-C bond formation. The images show five (meta-) stable states: (I) reactant basin, (II) approaching state, (III) activation state, (IV) product state and (V) product basin.
