A general question:
In COM pulling (pull two molecules away), does the weakest
inter-molecular interaction always break first? Or is it the
interaction aligned on the pulling direction break first?
Probably both. Whatever you do with SMD is path-dependent.
In other words, does every part of the molecule "feel" the pulling
force? Or the part close to the COM "feel" stronger force that the
part of molecule that is far away from its COM?
Forces are interpolated onto other parts of the structure, but as stated above,
whichever way you pull has implications for the outcome. It's not an
equilibrium process.
