Phys Chem Chem Phys. 2017 Nov 08;19(43):29162-29169. doi: 10.1039/c7cp06135h.

An experimental-computational methodology combining rotational data, high-level ab initio calculations and predicate least-squares fitting is applied to the axial-equatorial isomerism and semiexperimental equilibrium structure determination of fluorocyclohexane. New supersonic-jet microwave measurements of the rotational spectra of the two molecular...
