摘要: In this Account, the intramolecular hydrogen bonding (HB) properties of various proton acceptor groups (BXn: CN, NO2, CO, PO, F, CF3) with OH and NH2 (AH) in benzene derivatives are assessed on basis gas electron diffraction, spectroscopic, quantum chemical results. The most important HB energy, characteristic geometrical changes interacting (lengthening A−H B−X, shortening C−A C−B bonds) ring, vibrational AH groups. These particular interaction (in BXn pair single multiple hydrogen-bonded systems); however, they cannot be related directly to computed energies.
