title: Effects of Fluorine Substitution on the Microsolvation of Aromatic Azines: The Microwave Spectrum of 3-Fluoropyridine-Water.
abstract: The rotational spectra of the parent species and of four water isotopologues (-DOH, -HOD, -DOD, and -H(18)OH) of the adduct 3-fluoropyridine-water have been investigated using pulsed supersonic-jet Fourier-transform microwave spectroscopy. From the rotational constants, the structure of the adduct was deduced where the water is linked to the aromatic ring through an intermolecular O-H···N hydrogen bond with a bond distance of 1.9961(5) Å and an O-H···N angle of 156.8(1)°. The shape of the complex is such that the water oxygen is in the plane of the aromatic ring, on the opposite side of fluorine, and forming a C-H···N weak hydrogen bond with the adjacent aromatic hydrogen.
