摘要: Abstract Dihydrogen bonds (DHBs) as a sub-class of H-bond interactions are analyzed in this paper. The results studies on numerous DHBs obtained at the MP2/6-311++G(d,p) level approximation revealed. Different kinds investigated, from weak H⋯H attributed to van der Waals with binding energies amounting less than 1 kcal/mol, through medium strength, strong possessing characteristics covalent bonds. Bader theory well interaction energy components defined within variation-perturbation method have been applied here understand nature these interactions. relationships between energetic and QTAIM (Quantum Theory “Atoms Molecules”) parameters also analyzed.
