Relative Strengths of the O-H...Cl and O-H...F Hydrogen Bonds

摘要

Hydrogen bonding involves many scientific areas and is invoked to explain the energetic and structural features of inorganic,organic,and biological chemical systems.Herein,we show that a water molecule in a solvent-free environment prefers to form a hydrogen bond with a Cl atom rather than with a F atom.For this purpose,several isotopologues of chlorofluoromethane/water were studied by molecular-beam Fourier transform rotational spectrosco-py.
