Relative Strengths of the OHCl and OHF 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.[1], [2] 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 spectroscopy.
