✦ Synopsis

Two hydrogen-bond complexes formed between tetrahydropyran and hydrogen chloride have been observed by using a molecular beam Fourier transform microwave spectrometer. The rotation constants are consistent with C symmetry, with HCl pointing to the domain of the axial and equatorial lone pair at the oxygen atom (shown on the left and right, respectively). The axial form has been found to be the more stable one.
