Variational analysis of HF dimer tunneling rotational spectra using an ab initio potential energy surface

Oleg L. Polyansky, Roman I. Ovsyannikov, Jonathan Tennyson +4

A very accurate, (HF)${}_2$ potential energy surface (PES) due to Huang et al. (J. Chem. Phys., 150, 154302 (2019)) is used to calculate the energy levels of the HF dimer by solving…
