報告摘要：

Hydrogen bond is critical to this planet and mankind with its attribute and functionality remaining elusive. We show a three-body system to feature interaction between an atomic dipole X: and a molecular dipole R-Y, coupled by the X::Y repulsion, such as O:H-O bond for water irregularities. The O: can be replaced by a undercoordinated metallic dipole such as Rh:H-O for monatomic catalysis. Charge polarity inversion happens such as Cu-O:Cu for oxidation. Upon perturbation, the X:R-Y relaxes cooperatively its segmental length, energy, vibration frequency, and specific heat associated with polarization. This premise specifies a parameter space that features adequately the bonding and electronic dynamics in the frequency-space-time domains and the functional dependency of detectable properties for any substance involving X:R-Y interaction. This notion has insofar reconciled water irregularities, hydration interfaces, CHNO assemblies, and oxygen chemisorption, which inspires promising ways of thinking about atomistic catalysis, high-TC superconductivity, and beyond.
