Free jet rotational spectrum of the most stable conformer of 1-(2-fluorophenyl)-1-ethanol

The most stable conformer of chiral 1-(2-fluorophenyl)-1-ethanol is stabilized by a O-H⋯π interaction and it is at least 1 kcal/mol more stable than the remaining conformers. This is the result of a free jet millimeter-wave absorption spectroscopy investigation of the rotational spectra of the most abundant and O-d isotopic species.
