Multiple hydrogen-bonded dimers: Are only the frontier atoms relevant?
Non-frontier atom exchanges in hydrogen-bonded aromatic dimers can induce significant interaction energy changes (up to 6.5 kcal mol−1). Our quantum-chemical analyses reveal that the relative hydrogen-bond strengths of N-edited guanine–cytosine base pair isosteres, which cannot be explained from the...

| Sumario: | Non-frontier atom exchanges in hydrogen-bonded aromatic dimers can induce significant interaction energy changes (up to 6.5 kcal mol−1). Our quantum-chemical analyses reveal that the relative hydrogen-bond strengths of N-edited guanine–cytosine base pair isosteres, which cannot be explained from the frontier atoms, follow from the charge accumulation in the monomers. |
