Figure : Comparison of the relative interaction energies (ADF/BLYP/DZP) of ten conformers of 4A4E calculated with MFCC (pink) and MFCC-MBE(2) using a distance cutoff of 4 Å (purple) as well as in supermolecular calculations (turquoise). All interaction energies are given relative to conformer 7 and the conformers on the horizontal axis are ordered according to their interaction energy in the supermolecular single-point calculations.
