Abstract
The hydration of 2-fluoropyridine with one water molecule has been studied with a pulsed jet Fourier transform microwave technique. The rotational spectra of five isotopologues of the 1:1 complex have revealed the formation of a single most stable isomer. The observed cluster is characterized by an O−H⋅⋅⋅N hydrogen bond and a C−H⋅⋅⋅O weak hydrogen bond, where water is coplanar to the aromatic ring and acts in a double role of proton donor and proton acceptor.
