Background: Following set of data has been provided as a proof of general hypothesis for weak H-bonded and also VDW dimers. The methods of quantum mechanics have been applied are Hartree-Fock, Møller-Plesset, Density Functional Theory with state-of-art quantum chemistry software. And for this specific case results from NH3 dimer has been reported. [A]. The general hypothesis first proposed in a paper published online in 2020 and in archive in 2021 [1] with explicit mention of hypothesis that torsional electronic energy has singularities for weak H-Bonds contrast to force field results of energy continuum. [B]. This energy singularities are associated with quantum geometrical criticality of weak H-bonded or VDW dimers. Any QM energy computation method with reasonable basis set must reveal electronic energy singularities unlike smooth force field or molecular mechanics based dihedral energy continuum for weak H-bonded or VDW dimers. Also for weak H-bonded atoms if separated by a distance beyond bond length; internal rotation must show energy singularities; or equivalently geometry must show criticality feature in all QM energy computations. [C]. These QM computational results cannot be explained by classical reasoning because of no stearic clashes among atoms; molecular mechanics/force field always predict finite energy beyond bond-length. Hypothesis Tested: All conformational geometry in weak H-bonded or VDW molecules cannot be allowed as per QM contrast to MM even though no stearic clashes of atoms do exist; bond-breaking involves two aspects: sudden jumps in energy breaking of molecular geometry. The energy singularities results are indicative of geometry break-up or in other words bond breaking.
