Morphing a vibrationally-complete ground state potential for the hydrogen bond OC-HF

► A methodology for predicting properties of prototypical intermolecular interactions. ► Generation of compound-model morphed potential with radial shifting for OC-HF. ► Near spectroscopic accuracy for fitted rovibrationally resolved database. ► Only four adjustable parameters required in optimization to experimental data. ► Direct comparison of results with ab initio potentials.
