"WebSo once it gets enough energy to push it into an eclipsed conformation, it will quickly snap back into one of the two neighboring staggered conformations to minimize the repulsion. So the only way you can ever get them to stay in the perfect alignment required for the repulsion to be axial would be to cool the molecule to absolute zero(0K). " - Highest energy conformation

The

WebEnergy is a function of the degrees of freedom in a molecule (i.e. bonds, angles, and dihedrals). Conformational energy searching is used to find all of the energetically preferred conformations of a molecule (especially rotamers), which is mathematically equivalent to locating all of the minima of its energy function.
